I always have a hot drink and a cold drink available. My internal thermostat is totally off. If I'm not in a sweat, I'm freezing and can't get warm. This has been going on for 11 years.

I doubt I'll ever feel 'normal' again.
I'm still thinking about HRT as the dosages have been lowered alot (so I've heard) from when it was first used to treat 'M'. As for the other stuff, I am miserable without caffiene, chocolate, salt (felt like I was going to pass-out), etc., and never noticed a (good) difference anyway. I've tried the creme and many OTC remedies and most work for a week or two but then Not! So they are a big waste of money to me. Plus I hate taking pills of any kind... meds or supplements. I tried religiously even recently, but pills get stuck in my throat very easily, even when cut in half.
I highly recommend the use of a fan, the fold up kind you can carry with you. Works the best for me (when drinks aren't available). Good Luck, and I hope you feel better soon!
