I too have had the same thoughts, thoughts that niggled away at me. This is
only from experiencing various medications. Avonex was definitely bad for me,
as my doc said 'the cure was worse than the cause'. I've thought about why I
react like this and think I'm allergic to them. I take 1/2 doses of everything
and that seems to help too. I once read that, of course, the body is going to
react to new meds initially, that the liver and kidneys need to process
something they're not used to, but to persevere and the body will get used to it
eventually. So I have tried the meds and take what the body can adjust to and
otherwise just give-up the ones it can't adjust to.
