Oh, the Evening Primrose Oil is just absolutely AWESOME for pms, menopause.......all of that! I LOVE the stuff! I take 1000 mg of evening primrose oil along with 1000 mg of flaxseed oil and it really has been helping me with the irritibility that i have been experiencing for oh, probably at least 3 years now. I was always straight faced and never felt like smiling, i would become irritated very easily if things weren't done the way i liked them. all of these symptoms disappeared within less than a week of starting the epr and fso. How i found out about this was through a search i did for pscoriasis and this particular combination was listed to be very good at getting rid of or at least controlling pscoriasis. So far my pscoriasis looks.......a bit better and am hopeful that it will continue to clear up.
