If youve really added more raw into your diet than usual..sometimes that can cause more gas.....
Im not sure about the cramping...but that did happen to me before I passed plaque...
you might try to lightly steam some of your veggies..and see if that is easier.....
take it easy and be gentle on your body...
taking de-tox baths always help... check out the bath forum...
it sounds like your doing really well.....
you might want to wait to up the shake dose until your bloating and pain subside... maybe someone with similar experiences can add something....
