Hi Diane
Yes get off the diet coke, the aspertame might be a very big problem...so poison. I always tell my kids if your gona drink one get a real one at least your body knows that type of sweetener.
What has helped my perimenopause is progestrine cream and I started taking Dong Quai and ashwaganda...it has helped so much. The ashwaganda will give you energy too. That might help with your caffeine problem. Coffee is my down fall right now. Don't have alot of it but I can sure use a cup on some days.
