I Have Lived In Central Florida For 13 Years. I

I have lived in central Florida for 13 years. I am soon to be 70. I am being treated for bipolar with a low dosage prozac and bupropion, also low dosage because I am VERY sentisive to meds. My main allergies are cordisone and codeine. These past 2 years I sweat with very little exertion, I have exercise induced asthma, but have medically found no allergies here in Florida except the humidity, which is high.
Lately the sweating even occurs just walking in my home. I am overweight, no diabetes in our family, but this uncomfortable sweating is really a bother. Any suggestions?
