crikey,i was periomenopausal from age 32 to age 45,that's when the worst of the moody stuff hit. in our field,i REALLY had to watch my step,and remember that it was my body and brain reacting,not what a person was really saying that set me off.

i hit premenopause(officially) at 45,and the moody stuff stopped,but the hot flashes kicked in bad! unlike you,i've always had 'hot" hands and feet,but when my face and chest got hot,it drove me crazy,lol!  the worst thing for me was the cold flashes,my upper arms were FREEZING ,and my knees,about every 6 hours,i really hated that. 

in answer to your question,i had a full hysterectomy at age 49. and i still got hot flashes for about a year afterwards,and occasionally do now too,but it's pretty rare. i'll be 53 in the fall,and it this point,my poor hubby gets the hot flashes instead of me,lol!

i took a supplement made from black cohosh and valerian root during most of the time before my surgery,and it helped a great deal.

BUT. i should tell you that my MIL who took the hormones after a hysterectomy at age 28,she dealt with the moodies and the hot flashes anytime she stopped taking them. she had to stop taking the during her chemo before she died at 82,and it made her miserable,as much as the pain did. 

she told me not to take the prescribed hormones,and i truly believe she was right. like others have said here,try to do it in a natural way,if you can. and don't kill your dear OH! 😄
