[|Human|] I have problems in the mornings with my brain being in a fog. I have often taken Sudafed which has helped to clear it up and sometimes Excedrin, but I try to stay away from it unless I have a bad headache. I do have some problem with hayfever and the Sudafed clears up my congestion. I also take an antihistamine for hayfever. My question is: Is there anything else I could be doing about the foggy brain, because he slows down my thinking process?
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms may be related to the raised sinus pressure from the nasal obstruction. The fact that your headache is relieved by EXE Chat Doctor.  From the other hand, antihistamines can cause these symptoms (slow thinking and sleepiness) as a common adverse effect. Do you have these symptoms when you don't use antihistamines? What type of antihistamines are you taking? I recommend you to consult with your allergologist and try to find another therapy for hay fever (immunotherapy or a non sedating histamine). Caffeine (in the coffee) could also be helpful if you tolerate it well.  Hope to have been helpful! Best wishes!
