thanks again for the help. yes my wrists crack all of the time too. my right shoulder is the worst but i am cracking everywhere these days. i have been on the diet for about a month now. made the mistake of eating an apple yesterday and today and the pressure in my head is back. oopsy! i thought it was time to try and introduce a few normal foods because i have been so strict but i guess i was wrong! i do take vitamins - garlic pills - homemade yogurt - and yes i am trying threelac since it seems to have helped some (i figured it couldn't hurt to try it). i am going to try the jerusalem artichokes for another probiotic. someone told me it helped them tremendously. thanks again!
