It's 4 a.m. I've been up since 7 a.m. yesterday. My period is about two weeks late. I'm 48. I get hot flashes intermittently. I'm in the process of getting divorced, I'm caring for aging parents, my sister and her husband lost jobs and are now moving across the country for a new job (so I'm stuck with all the elder care now), and I'm trying to finish my last year of college (double major).
I just want to sleep...I want to go to bed at 10 p.m. and get up at 6 a.m. And wake up refreshed and full of energy. But I usually just lay in bed while my brain churns and my heart flutters and I'm wrestling with the sheets and blankets. So I get up and try to get some studying done...but brain is too sluggish to function intelligently!
I'm currently taking a handful of herb supplements and vitamins for all the issues. Nothing is working very well.
Okay, I'll try to go to bed again...

I went thru the same thing when it was at it's worst; and yes, peri-menopause can come and go in spurts. Mine is much better now than before (it started when I was 46 y/o). The hot flashes are much less; only now and then, but I'm now 50, but I can tell when my hormones are reeking havoc in my life -- I get weepy and easily irritated and hungry, etc. Some nights I can't stay awake and other nights, I can't sleep. I'm learning to roll with the punches, so-to-speak. 
My doctor put me on METFORMIN to help regulate my body's own hormones better, get my blood sugar levels back to normal (a success), and help release water retension problems in my legs (this does help). Some say there is a side benefit that it may help you lose weight, but I don't know about that for sure. I don't want to take these forever either as some of the side effects bothered me in the beginning; now they aren't as bad.
