Susan you sound just like me. I cannot take major chelation agents with any degree of success. You think DMSA makes candida worse, i definitely wouldnt try ALA. I was nearly suicidal after using that stuff. Im also pretty sure i have lyme disease too. I was bitten by a tick in 2002 on my neck and ive never been the same since. However i know the mercury was the turning point, i felt like death after having my amalgams out. I honestly think your best bet is to heal your gut and maybe take something like cilantro, just a little in your food, see how you tolerate it. Russ sells Algin and that worked OK with me. My stomach is so sensitive too. For candida the only thing thats truly worked for me is Formula SF722. its awesome and is very gentle on your stomach. Leave chelation alone right now...i really would. I have MSN messenger [email]wildheartxxx@hotmail.com.[/email] If you want to chat, you truly do sound like me.
