One week is awesome! Congrats!!! Regarding the exhaustion, mine lingered for a couple of weeks. Going to the doctor is a great idea. I'm at 42 days and am doing much better, but still have ups and downs emotionally. It takes a while to get "all better". I must admit though, I feel better physically and emotionally than I have in years. I can't wait to be 100% all the way around.
Congrats again! Keep up the great work!
