I'm 3 mths in with Tamoxifen. The flashes are the pits. It gets embarrasing at work at times, as I will literally start dripping has happened a few times when talking to a customer.
At home I am using a "chilly towel" (found it at the chemist) that helps, as does the moisture wicking sleepwear, not waking up in damp sleepwear and having to get changed. It alleviates it somewhat, and is worth the money - especially as I live in the tropics. I also have ginger "Travellers friends" (from Buderim Ginger) that I have to help with the occassional nausea. These are individually wrapped and easy to have on hand (handbag etc)
