You sound just like me! And mine is always so heavy the first 2 days it is tough to work out around that. But, like others I find it does make my symptoms better.
A quick anecdote:
My sister and I did the Houston marathon this year (1st one for both of us). That morning when we got up she visited the restroom in our hotel for one last time before the marathon, and she started. We quickly tried to figure out how to stuff a few supplies in our already overloaded small pockets. She did the whole marathon and only stopped twice for a potty break. What a woman! I probably would have stayed at the hotel and skipped the marathon. She is 43 and so awesome! When I lack motive I always picture her in my mind!
Lots of luck,
Lynn
