I haven't noticed any changes in libido, but I have definitely gained some fluid, and prolly a bit of fat on P7. Sleeping better though. I recently stopped the P7 because of uncomfortable PMS symptoms that I'm trying to determine the source of. Sore breasts, huge appetite for "bad" foods, foul mood and reduced body temperature....It may be the P7, it may be my age, or something else entirely.
I'll keep you posted as I learn more. I suspect my experiences have more to do with perimenopause than P7, but I don't know for sure.
