I was lucky with Tamoxife, no real side effects. I gained weight and noticed vaginal dryness, but that is all. No hot flashes or other side effects. It all varies greatly with each individual and also varies by age. No two of us will have the same experience....
I would encourage you to try it and see what happens. If your side effects are bad or your quality of life changes, then consider stopping it.
Go for it!
