Indigestion problems..tamoxifen??

Hi everyone, I’ve been on tamoxifen now for over 6 months, had the usual hot flushes, joint pain etc… What I’ve been getting more recently is terrible heart burn! I had it when I went through chemo, but seems a lot worse this time, I’m cutting out carbs, like potatoes, pasta and rice, to see if that will help, has anyone else had this problem, don’t know if it’s long term effect after chemo, or is it the tamoxifen. Trying all the usual natural remedies.
