Pulled in two directions!

I'm really torn about meds. The 3 mil. units of Interferon have been working well. But, it tends to mess up my days with my wife due to fatigue and light headedness. These other drugs, ie Pegasys, Interferon b-2, are tempting because of the potentially lesser side effects. However, if I switch meds at this point in the game, I may risk the growth restarting. I know! I do plan to talk to my Dr.. It's just that my appt. with him is 2 wks away.
