I have been taking these tabs for 2 years nearly, at 1st i went on 1mg which helped with the hot flashes and sleep problems but after a few months realised i needed to up the dossage as the hot flashes had started to come back, i was not sleeping again feeling really down again. I now feel back to square one! ( No sleep problems or hot flashes)Its just a day or 2 after starting the white tablet i feel really down,aggitated fed up...
