Help.... Been taking Tamoxifen for six /seven months now and have started to take citalopram to help with the hot flushes and sleeping, I've tried taking morning and in an evening to see if I feel any different. Some months are better than others and after all I've read think it may be the brand of tablets although my pharmacy doesn't agree, I'm wondering if I should go back to the doctors and tell them the citalopram isn't doing any good, I've gained almost two stone in 7 months which is causing me stress just feel at the moment I'm in a worse situation to when I was going through the chemo just feel so alone at the moment....
