Mine aren't too significant, although I lived pretty "healthy" before. The biggest change is that I now sleep through the night, I used to wake up 5-6 times for no particular reason.
Even though I lost only 25lbs, my snoring when I am not doing any alcohol has been greatly reduced (according to my wife).
At 46, I am finally able to grow sideburns, and could also do a beard if it wasn't 105 everyday. No such luck for the top of my head though.
I usually have a summer flare up of rosecia (sp) or some such facial rash that has not flared up in two seasons.
