I will put my 'two bobs worth'in here ladies!! I am almost at the end of 2 years on Tamoxifen.My oncologist told me that things would settle down,and she was right!!! The first few months were terrible.Day and night,and I really started to feel that it wouldn't improve.However,for about the last 3 months or so,I hardly have them at night any more.I do wake,and often have a mild hot flush,just as I wake,so I guess that means it actually woke me.But no more than once or twice a night.It used to be dozens of times throughout a 24 hour period.During the day,they are almost non existent,but I definitely know now what can cause one.Coffee or tea,being stressed,feeling upset etc.I have proven this to myself over and over again.Things that have helped me over the months are: cold drinks( to cool your core)sleep with an oscillating fan right next to the bed,winter and summer.Wear only cotton,and only layers.Dont just wear a jumper that you can't take off.A chillow pillow....mine actually broke,but it was great while it lasted,and I don't need it now.Cotton sheets with a high thread count,as they are lovely and cool.Take care and hang in there :):) Cheers Robynxox
