I ended up taking Gabapentin to shut down the fire ants in my armpit following my recurrence and subsequent surgery. It's not a great drug for a variety of reasons, but it does have the added benefit of stopping the night sweats. It also has something of a sedative effect so I sleep better, and sweat less, if I take it. My dose is quite low and while I'd rather not take anything that screws with your brain the way high doses of those drugs can do, it's an acceptable compromise. I tried endep, but it didn't agree with me. I think you have to tinker around with this stuff, maybe it gets better with time regardless of what you do, maybe its the pharmaceuticals. I don't care, as long as I get some sleep.
