hello,
i did three months of nine primal defense a day last jan.-april. it made me crazy.....yes, what you are experiencing is die off. it is a wonderful product and it totally turned my health around, although do not expect a cure-all in any product. i cleansed so hard on primal defense for the entire three months and emerged feeling like a different person. you must start slowly and work your way up from one a day as you can. it is worth it. hang in there. i am now doing a three month stint with threelac and my health continues to climb every day...though the die off is still intense. getting rid of this stuff makes your body sick. there is little way around it if you desire to get better in a more timely fashion. listen to your body, but don't give up.
good luck,
tif
ps. do home enemas or colonics to wash out the yucky stuff as you cleanse. i am also doing the "body ecology diet" by donna gates. digestive enzymes with every meal are a must.
