Suggest Treatment For Hot Flashes, Restless Legs And Itchy Skin

Question : I am never physically comfortable for more than a few minutes - either I have a hot flash, restless legs, post-shingles itching/pain, or simply become overheated. This doesn't change with exercise, changes in diet (within last 2 months changed eating habits, losing weight to prevent diabetes type 2 onset - successfully reduced a1c from 7 to 6.2). Shingles outbreak was late November, 2015 - zoster sine herpete upper left thigh. I have daily itching and/or pain (pain is not comparable to initial outbreak: I would give that a 9... This is more a 5). I prefer room temperatures in the 50s to low 60s which is unrealistic - most find that unappealing. The lack of ability to be comfortable even for short periods is impacting my mental state. I am irritable and can't relax. I am having trouble concentrating. My lifelong familial tremor (left hand) is worsening. The only relief that I have had is narcotic (1 vicodin), but that is problematic for all the obvious reasons and more. First, stronger narcotics make me ill, and even with Vicodin, I can only take it at night. For that matter only at night once every 10 days or so, or it doesn't work. So that's not practical unless I am willing to accept one decent night's sleep every 10 days. And, this isn't just a sleep issue. I have tried SSRI meds for the hot flashes. They don't work for me and they make me feel weird. I tried Gabapentin, which didn't help either. I am out of ideas. The restless legs symptom is recent (post shingles).
