I am 47 years old, and for the past 4-5 weeks, I have had sudden onsets of profuse sweating that occurs mostly while I'm asleep and seemingly often before my alarm sounds. However, it happens during the day but it seems milder. I had a parathyroid glad removed in December and am wondering if this has anything to do with these attacks. I also go from being extremely hot to extremely cold after the flash of heat. One more thing, I am having a difficult time getting my bowel movements to be regular. Miralax doesn't work and I took 3 Ducalax tablets Sunday evening, was haven't had a movement since early Monday morning.
