Your story sounds a lot like mine.
I too have constipation now and am feeling doubt over 100% raw being the solution.
I'm suffering from eating disorders now... sth I never had before raw. I thought it was a process... but now I'm not so sure. I always ate little because of digestion problems and I never would have imagined I would be bingeing every other day. BUt after much research I suspect that the problem is parasites.
I felt much better after doing a parasite cleanse like Humaworm and realized that a lot had to do with parasites because after cleansing, I passed Gallstones (just on its own, no flush) and digested much better. I'm going to start a second one next month.
Your problem may be parasites as well. I suggest you go to the parasites forum here and read to find out.
I do hope you find your cure.
