Glad to hear you're feelin' a bit better, Fred. I went on Metformin a year ago and other than the occasional case of the trots, have suffered no ill effect. I presume it has reduced the glucose levels, but I've no anecdotal evidence.
I was feeling pretty good, but the doc started me on a statin after the last appointment (despite near normal cholesterol levels) and that stuff has kicked my tail. I'm frequently experiencing exhaustion after any sort of semi-vigorous exercise like mowing the lawn, painting, or even puttering around in the "garage". Hopefully the body will acclimate soon and things will return to normal (whatever that is).
After losing 60+ pounds, the weight has been creeping up a bit. I lost my morning walking buddy and that regimen has declined sharply...need to get that started again and get the weight back down.
I visted my former walking buddy a few weeks back...he looks good, me not so much:
