Gabapentin
"Have suffered intense hot flushes up to 20 times a day/night for the past 5 years am 49 years old and they were really affecting my life. I am unable to take HRT and was prescribed gabapentin by my GP gradually increasing the dose up to 400mg 3 x a day my hot flashes have reduced by 90% still having the odd one which is much milder than before so hardly notice it at all. This medicine to be honest has given me back my life I feel like a new woman. Sometimes I feel a bit lightheaded on these tablets but nothing to bad and now sleep like a baby. If you are considering giving these a try don't hesitate."
