He felt groggy for a while but after getting the booster shot he felt better like he is diabetic and his glucose level went to normal after getting the booster shot." Anatomical site of administration of the vaccine: Consumer stated, "Sure, left arm, upper arm, the shoulder." For all the shots: Consumer stated, "Yes, all shots." When paraphrased the concern, consumer stated, "Yes, there is no concern, just information. Yes, wasn't too long afterwards that all of the interesting things that happened, sometimes things just do not smell or taste right and I don't mind, I don't like most of the things anyway but that's one thing that changed and I had problems with glucose levels for years, like I am diabetic, like a dozen major health problems (Intent History). I am on a ton of different medications, about 5 or 6 just for diabetes and I had trouble controlling my glucose levels and after I got the booster my weight has gone down, my glucose levels kind of stabilized and for almost an entire week my glucose levels were actually low. I stopped all my diabetes medication (Further not clarified. Hence, captured as event conservatively and suspect captured as unspecified medication.) and my glucose levels would keep going low. Usually normal for me is like 150-130. When I usually go around a 100 or even a little longer at 100 I start to feel shaky sometimes it was going down 68, 67. I ended up to drink sodas and all sugary stuff just to get it back up (Intent treatment) and that is without the diabetes medication, completely stopped taking it. Now, I am on and I would just stop regularly, if it starts to go high, I start taking some of the regularl stuff, some of the normal pills and injections."
