Everyone is different. Some ppl get side effects shortly after starting the med and others tolerate tamoxifen well. Just give yourself time and try not to focus on side effects that may or may not occur for you. Live yiu life as you do. Maybe exercise- walking is always good snd eat healthy. Drink plenty of water etc. Try and stay positive on terms of the tamoxifen and the benefits. I had taken tamoxifen years back fir 3 1/2 yrs without any side effects. I stopped it early if the 5 year protocol as it had started effecting my hair. My oncologist was ok w/ me stopping. Good luck.
