Additional information: He was dealing with insomnia and a motion body feeling where he was constantly moving from left to right. Patient stated the motion feeling happened right after the second dose of the vaccine and it dissipated after three weeks and he does not have that anymore. Patient stated from the first to the second shot it created an insomnia bubble and he has never had trouble sleeping before the shot and staying asleep for a certain amount of hours. Patient stated he was now having trouble sleeping, getting to sleep and asleep for a night without waking up. Patient stated since the first shot he has been sleeping poorly and then it got worse after the second one and he went 3-4 nights without sleep whatsoever not even 1 hour, 30 minutes, or 10 minutes of sleep. Patient stated he went to the hospital and then to a doctor who prescribed him a medication to knock him out which was able to do some. Patient states from the first to second shot he was able to get 3-4 hours maximum of sleep and then after the second shot he got 1-3 hours maximum of sleep every night then it went to no sleep for a night to 3-4 nights without sleep. Patient stated he also got chills, fever and all those things posted online he experienced all those symptoms and then the additional symptoms not listed after three weeks that included the motion back and forth like vertigo and then the insomnia. Patient stated he was prescribed Lunesta 3 mg a sleep medication that should knock you out cold for 7-8 hours but he was still waking up after 2-3 hours. Patient states he saw a huge change in his sleep on 23Aug2021. Patient had insomnia or motion like feeling from left or right similar to vertigo being reported as a side effect from the Pfizer COVID vaccine.  Patient states he felt like Pfizer was the blame for side effects that he is experiencing because he never had these issues before taking the vaccine shots. Patient stated it doesn't make sense why this would come up out of no where after taking the shots. Patient stated this insomnia has to be corrected and you have to find out a way to correct this. Patient got response and was referred to HCP (health care professional) for treatment recommendations. No investigation assessment was done. Patient was calling because he got some side effect through the COVID vaccine shot from Pfizer and very serious side effect to the point when he first got the vaccine he got the symptoms that were pretty much similar to what was mentioned in the CBC website and probably your website and it were normal symptoms but then that extreme exclusively to the point of he actually having a weird thing that he guess it affected his brain to point of almost giving me vertigo with the motion back and forth like a rocking motion or a pendulum motion you know the pendulum, pendulum motion, clock, so he got so it kept moving me back. When he am saying he got from this vaccine the normal severe chills and fever and everything that was there the you know all the stuff that was there he got everything that would be normal COVID symptoms that probably be the vaccine he got that than he also got something that was more serious the motion back and forth that was waving literally his body from like it was moving forth when he was standing still or sitting still or in my bed still he felt like constantly being moved from left to the right than my bound was like not like and that lasted for bunch of weeks now he don't have that right now which is the good thing that he don't have the motion right now that lasted for the last week and a half he guess but the thing which he was really concerned with the vaccine was that he had insomnia that was created from sleep problem like he had a sleep disorder from taking 1st vaccine, so the 2nd vaccine it got worse from the 2nd vaccine the sleep disorder where he can feel like now I cant go to sleep without anything that called prescription he cant even stay asleep get a good nice sleep even with prescription drug (Un-specified Medication) and so he went to a bunch of doctors and I even went to the hospital. 4 nights without any sleep at all which was like maybe he have died like whole body shut down it was like 3 to 4 nights for sure with no sleep, not an hour no sleep and it all relation to the vaccine he never had sleeping problem before he never had any issue before with breathing thing and ever since he took the vaccine 1 and 2, he have been having all of these problems and health issues. Patient did not have other medical condition other than Pfizer vaccine have given me. Patient stated that right now doctor had put me on a medication which is Lunesta the Generic form of Lunesta. Patient reported as a treatment for the side effect the medication name is the Lunesta is the actual regular name for it is Eszopiclone, 3 milligrams. He was taking some previous medicines from another doctor who administered some other sleep aid and observing dieting medicine they saw my symptoms and issues and were on this is what I am on right now. Patient stated that he was trying to figure it out exactly he think it was 02Aug of the 1st vaccine he was trying to look for his card right now my vaccine card. So he got the 2nd shot 23Aug and he should have got the other one 8 of 2 so he got the vaccine shot on 8 of 2 on the Monday and than he got 2 one on 02Aug.  Patient had a side effect from the vaccine and it is stopping me from doing my daily routine and stopping me from sleeping. He never had an issue at all before the vaccine with sleeping now he was being prescribed medication a doctor which is for getting me sleep which was not even getting it from regular night sleep from the hours that I get so this is really serious and Pfizer vaccine is definitely the cause and catalyst in all these issue and that was what upsetting me. Patient said that he never had trouble sleeping before and I have issues now since the first vaccine and then even way worse to second vaccine where he wasn't sleeping well at night with the first vaccine and then the in the second vaccine he actually got so bad where he couldn't sleep at all for like days without actually having a prescription medicine. Patient said that this vaccine has screwed up my schedule, has really messed up his schedule with breathing and is the second, worst second it affected my livelihood and he was very much concerned.No follow-up attempts are possible.
