Hi, I've been on tech for about 18 months. I didn't really have any major side effects, minimal flushing but I am about 2 stone heavier as I took the "high fat food" a little too literally. My biggest issue was/is remembering to take it!!

When I first started taking it I have to admit the side were brutal, agonsing stomach cramps were the main problem. My ms nurse encouraged me to hang in there though & she was right after a few weeks my body adapted. I still get a hot itchy rash quite often but that usually only last about an hour then dies away, so it's manageable. I recently saw my neurologist & was told that in the year I've been taking there are no new lesions so it seems to be doing its job. Good luck!
