When things get REALLY BAD for me, I use the oldest trick in the book:
1 tbs. apple cider vinegar in 1/2c. warm water right before bed
Trust me, you will wake up in the morning and empty out. So much better.
I don't recommend doing this often, just when you're very uncomfortable and nothing else is working!
Lately, I'm drinking a lot of hibiscus tea and dosing it with alfalfa tincture. That seems to help keep things regular--that and snacking on raisins!
