I have taken Imitrex tablet on and off over 3 years, I have had burning sensations, blurred vision and no muscle control, I felt like I was in a daze and had dry mouth as well as pains. I had been using a beta blocker to combat the migraines day to day but with using Imitrex I gained poor judgement and lose of memory, upon talking to my doctor I stppoed taking both drugs and have not had any side efeects in 3 months
