Kulkuf is enough! I was sceptical at first, but WOW, it stopped my night sweats and allowed for a good night sleep, just like you said it would. I wear mine all night and just push the button when I have a hot flash and go back to sleep. The five-minute automatic cut-off is a great feature. I also use it in the mornings while getting ready for work. I love it! I carry it with me everywhere. I never know when a hot flash might occur. Thank you KULKUF!
