Tamoxifen, is there anyone out there who HAS NOT been suffering awful side-effects?

Hi Mightystar, I still have insomnia even though I've switched to Zoladex and Letrozole. The brain fog did lessen over the months. You are still recovering from active treatment too, which also contributes to the fatigue and compromises your immune system. I've not experienced reflux, but Tamoxifen did cause constipation!  :/
