After TC Chemo-Frequent, Daily Hot Flashes

Hi; I finished chemo at the end of July, last year. Was 45 then; turned 46 this past December. At almost one year out from my last chemo infusion, I'm finding that the most challenging side-effect is the regular cycle of hot flashes, every day and every night. My medical oncologist tells me that chemo pretty much pushed me into peri-menopause. Roughly since November/December of last year, I've been experiencing hot flashes every hour of the day. Night sweats are are pretty bothersome, too. I currently take Tamoxifen on a daily basis, so trying to ease the hot flashes with hormone replacement therapy is not an option. Right now, I'm waiting on my health insurance to approve a prescription for Effexor, an anti-depressant that has apparently been found to ease hot flashes. In the meantime, I thought I would ask if anyone knows of any other non hormone-based treatment for hot flashes and night sweats... an intervention that would not be problematic alongside Tamoxifen. Any and all ideas would be much appreciated!   ~ Christine
