Hi Hermit, welcome to peri-menopause. I'd say you are there from the symptoms you are describing. I found some of the most up to date information about hormone replacement therapy, bio synthetics, herbal remedies, diets and such here:

I went through surgical menopause so I didn't have the gradual changes and symptoms of peri-menopause. I went straight to the big M the day of my surgery. I remember feeling really tired and didn't have the same energy. I also saw my weight sky rocket not 6 months afterwards. It will take an act of God to get this weight off but I'm gonna try. I found cycling for a min. of 90 minutes actually does more for my weight than any activity. I guess I need that sustained cardio benefit to burn those calories and tone up.

Hot flashes were the worst and I found that by eating soy protein it helps. Sweet potatoes are also shown to reduce some of the symptoms. And those flash temper moments can get UGLY. It's another moment brought to you by the hormone. I feel it coming on, like an adrenaline rush and it drives me cuckoo. It's better I stay away from people at that point.

I found my sleep pattern changed and am on an Rx (non-habit forming). You might find relief just taking melatonin at bedtime IF you don't already have sleep pattern disturbance.

I hope this helps and hang in there. It does get better a little at a time. Just keep cycling and eat good food and it will help diminish your symptoms.
