Thanks for stopping by lodonnel. The bright side is those symptoms passed (no pun intended) after the second day, and it's been smooth sailing since. I'm still at the very beginning...10 days in...but I feel better than I can remember feeling since I was in my 20s.
Best of luck and good health to you on your new program, and come on back to the forum if you have questions or need support. I've found people to be very encouraging and eager to help.
