anyone start getting side effects from asacol after you've been on it for over a year?

i've been on asacol for almost 2 years now and all of a sudden i'm nauseated off and on all day. it's been going on for a week now. i suspected a virus or something last sunday because i had nausea and lots of D. but now my BMs are good and i'm still nauseated.
i don't think i'm pregnant (very very unlikely that i would be) but i'll be taking a test today or tomorrow to be sure.

just wondering if anyone started getting side effects from asacol after you've tolerated it well for a long time.
thanks!

I took it for 5 years and the only problem i seemed to have was dry eyes, the tiredness came from the bloodloss, with this came the sleeping longer than i was awake, i was diagnosed a week after comming home from my honeymoon and fortunatly we had no childeren so the sleeping thing was not a great problem.
My new wife (one and only) was so supportive it hurt me somtimes because of what i thought she was dumped with, however my story did get better and i hope and pray everyone who suffers does too,
