It might be worth posting on the Chemotherapy thread as well so there might be ladies on there who are on tamoxifen and are/have experienced this.
Sorry that you havent received a response as yet, hopefully this post will bump it up for someone to see.
There is an older thread that talks about weight gain on tamoxifen which you may find helpful to read whilst you are waiting for a reply.
User Lemonlush is still active on the Forum and she was active on the thread mentioned above.
