I know what you mean. My wife is always cld and I'm always warm in bed with as little blanket on me as possible.
The sweating was a problem with meth that never went away, but it wasn't aproblem with oxy or morph or the meds they ave me on now. I ddo remeber seating uncontrolably after surgery when using PCA dilaudid, but like SS said, that's a side effect of opiates. They do cause flushing. NOw I'm back to just warm naturered, I mighht feel a little ho flash frm time to time from using BT meds, but not the change your shirt 3 times a day because your drencing it sweat. I had to put up with that prior to the pump when I didn't have prescription nsurance. The only med I could afford was meth and sweating was a nasty side efect. Any amount of exertion or sometimes none at all and sweat would soak my hair and drip from my nose and I would have to change shirts.. Keeping your hair short helps a little. I do think this will get better with time and you will be your same old, warm blooded self minus the hot flashes.
I think most folks do accomadate to that side efect. It seems continued problems other than with methadone do tend to deminsih over time. I've read thousands of posts over the last 7 years and it really doesn't seem sweating from oxy has been an onngoing problem or complaint of oxy users. Meth never stopped but the hot flashes of oxy did deminsh with time for me, not that I ever really found a right dose of oxy. The doc that started me onit, had her mental limits. I had to cange docs due to insurance issues and my new doc doesn't prescribe OxyC. I live in VA where th stigma of a few posckests of abuse got media attn annd purdue created the first OPxyC trackng system as a way to combat this. It just draws too much attn from the DERA so he doesn't take that chance. It's his chice to avoid the oxyC radar and I can't blame him for wanting to be able to help everyone that willl benefit from some other drug without the DEA constantly in his ofice.
Not to discont SS, It's nice to hear all women don't have pop cycles for toes and the "I'm cold" complaint year round.
Flushing is a classic opiate side effect. Hopefuly one that will deminsih for all that suffer. I wouldn't be as optoimitisc if the med was methadone, but I had good luck with side effects deminsihing from oxy.
Oxyodone is the med I choose for BT pain with a pump deliverying dilaudid now . Sweating hasn't been an issue for years since the pump was implanted and I stopped methadone.
Good luck, Dave
