I had severe episodes from age 14 to 19. Read in newspaper column that some people are SEVERELY sensitive to caffeine. After quitting coffee etc, I had NO problems for YEARS, until lately without thinking I was eating coffee ice cream from the US. Once I put 2 plus 2 together, I stopped the coffee ice cream and fine. That med you are taking has bad side effects. At age 75, I take NO meds for anything. I investigate the CAUSE of the problem.
