I'm wondering if any of you who are taking Tamoxifen have problems with stomach aches and nausea. I've been on Tamoxifen since the middle of July. I didn't have any problems at first, not even much trouble with hot flashes, but in the past two and a half months on an average of about once every week and a half to two weeks, I get this stomach ache that really puts me down. If I take a Zofran, it usually will subside in about an hour, but a couple of times I've just plain gotten sick. Have any of you experienced anything like this?
