Could be the extra toxins are causing a back up. Your liver gets overworked. Are you taking any liver supporting herbs? If your gut is really leaky it can cause it as well. I think this is my problem.
God I'm the queen of constipation. I really had a total shut down and I'm blessed my body held up for so many years like that. Dumb %&* doctors. My husband was talking the other day about this one guy I went to who's response was to eat more fruit. It's real upsetting to think back on that and that I could have gotten better so much easier if I'd have known what was wrong. Oh well. You live and learn. We've all been there.
My only option is enemas when it gets too bad. You can buy a bag from one of those small mom and pop pharmacies. Herbals used to burn me alive so I definately know where you're coming from. Yikes. I remember those awful days. But I don't get that way much any more due to the sauerkraut.
