I woke up in the middle of the night to use the bathroom. I'd taken Dulcolax (a stool softener) before bed and I also had some ground flax seed in kefir. That worked! For 3 days, I couldn't go! I also couldn't get BACK to sleep because my left leg was hurting. The whole leg from top to bottom ached and was painful. Switching positions didn't help. But it's okay this afternoon thank goodness. I skipped the gym this morning because it was so painful!
