Mine was easy too, no hot flashes or anything, don't even know when it happened since I had the IUD. but got the MHT, low dose estrogen & progesterone, because I was getting bladder infections and worried about osteoporosis (family history) realized I did have some symptoms because my balance came back (standing in one foot balance not like mental balance) and my thinking cleared up some, I was foggy but just figured it was normal. I freaking love this routine except for the fact that it's made me medium sized rather than slender, which is a mindfuck - I feel really good otherwise, both in body and mind. And the weight gain increased my bone mass so I can't even lose it.

I think it's 50% of women get symptoms like hot flashes - that's a big chunk but certainly not everyone.
