Being constipated alone makes me feel panicky. PMS makes me feel aggressive. (I don't have it anymore, as my hormones are better balanced.)
There are herbs added to cleansing mixtures that are included just to reduce or handle the flatulence. BTW, congrats, it sounds like big die-off.
Get an enema bag and do some! I put it off, wondered what good it could possibly do,.... but now I'm sold on them. Take your time and feel your way along - I bet you'll feel a lot of relief and much more control throughout your cleanse. I was too squeamish to start them until lately, but had to finally admit that all the people who like them, couldn't be wrong.
