I took anas. for 4 1/2 yrs , did ok . I just wanted to say I take pickle juice , and eat pickles and leg cramps are never a problem for me luckily . I have told other ppl this and basketball players have said pickle juice helps , for that very reason . Not scientific , just anecdotal , but won't hurt to try it . Good Luck ! PJ

Yes, I had leg calf cramps from tamoxifen. Potassium helped enormously! I also had hot flashes, mood swings with crying and rages, AND chemo- brain. Journal of Neuroscience. Mark Noble, PhD Sept. 17, 2013. Mental Fog with Tamoxifen is Real.

yes, I did. On anastrozole, Letrozole, and another. I gained a lot of weight on tamoxxifen and stopped all of them after 6 months.... I now eat WFPBNO, have lost 56 pounds, and have neverfelt better. I walk 2 miles a day, and am 4 moths due to my 4 years clearance. The drugs caused me terrific pain, I now have psoriatic arthritis and not able to use my fingers. The side effects were terrible.

Hi, yes, i was also getting bad leg cramps nightly. My doctor checked my calcium level and it was low.
I started eating more leafy greens and a supplement and that got rid of them for me.
I hope yours go away soon.
