Can Tamoxifen cause loss of appetite?

Weight gain or loss is listed as one of the side effects on the prescribing literature. I've seen several women here who say they lost weight on it.

I've been taking tamoxifen for a little over a year, and I, too, have lost my appetite. I have to force myself to eat. Nothing tastes right. Also, I have dry mouth and increased thirst; I feel crappy all the time (low mood, extreme fatigue); and my hands hurt like crazy. Spoke with my medical oncologist yesterday who suggested taking a four-week break from tamoxifen to see if I feel any better. That way, I'd know for sure whether it is indeed the culprit. She said her only fear is that I'm going to feel so much better that I won't want to go back on tamoxifen. That tells me something right there. After looking with my doctor at the longevity data, with and without tamoxifen, on the Cancer Math website, using my specific info (age at diagnosis, staging, size of tumor, lymph node involvement, etc.), the evidence to stay on it -- in my case -- isn't terribly compelling. I'm going to take the four-week break and see for myself.
