Still going after over a year. I try not to dwell on the stupid sweats as it only depresses me. I live coat on coat off, covers on, covers off. Summer was worse as it used to start as pin pricks over my torso and that's pretty hard to grin and bear it in public. Nearly froze last evening. Tip: Never commence a late evening walk on the beach during a hot sweat. It was heaven for the 5 mins of the sweat and then 25 mins of nearly freezing because I forgot the coat lol.
