Cold Sweating/Sleep Issues Becoming Unbearable

Over the past month or so (this has happened during past winters as well but not as severe) I've been noticing my sweating, specifically armpits, has become beyond excessive. This is common for me in the cold, but it's hit the point where no matter what temperature the room is AND no matter what temperature I feel I am in the moment, my armpits are literally dripping inside my clothes. All four combinations cause this - cold body/cold room, cold body/warm room, warm body/cold room, and warm body/warm room.

Additionally, for the past 3 weeks, I have been unable to sleep through the night. I have probably averaged 5 hours of sleep per night, usually in multiple parts with vivid dreams and multiple bouts of simply lying in bed frustrated with my eyes closed for what feels like far longer than I'm sure it actually is. This has added to all aggravations, made many other symptoms worse, etc, but the sweating is the most periodically frustrating.

It used to only happen when I was Very Cold or Very Hot, and taper off once I started to equalize with the room. Now it's about half the day, on and off - possibly lining up with certain medication interactions, but also all through the night, thus adding even more to the sleep issues and continuing the feeling of spiraling.

I take gabapentin 400mg when I wake up, around 4:30pm, and around 10-11pm. I take vyvanse 60mg around 2:30pm, and on work days, I take adderall 20mg at around 8:30-9am. I notice the sweating the worst (besides at night) starting around 4pm consistently and lasting for a few HOURS nonstop.

Does anyone have any suggestions on how to make this stop??? I am really struggling and feeling like things are slipping out of control more and more. I have to do twice as much laundry. I'm so tired. Happy to give more info if it helps, and thanks in advance.
