I know exactly what you mean. My doctors has yelled at me for the past 6 months about my weight gain, higher cholesterol, higher blood sugar readings...even gone so far as to tell me I may have to be put on insulin rather than the pills I'm on now for my diabetes. All of those things are side effects of the Arimidex I've been on for about 16 months now, but I still get yelled at.
Some of the other side effects I've had are sleeplessness, nausea and vomiting, sore and stiff joints, and some I can't even think of right now. It bothers me to think I still have to be on Arimidex for over 3-1/2 years. I can't help but wonder if I'll feel like I'm 90 when I turn 70 in 3 years. LOL.
But if it continues to work, I don't really have a choice.
