I was lucky enough to have acupuncture sessions via a cancer therapy charity to deal with hot flushes, they really helped for me highly recommended, also help with relaxation etc I was really impressed with the acupuncture. My hot flushes were pretty intense, still get some now despite finishing Zoladex over 2yrs ago - seems like I'm going for the length of time on treatment, 3yrs, to get over all(?) side effects. If you have something like a Maggie's close by ask about acupuncture or GP may know. I needed a letter from GP for the charity to 'prove' cancer treatment, understandably.
