The IV DMPS is excellent in my opinion, nothing compares to that. I would also take the IV EDTA if they offer it to you, because chances are good, in this world, you have other metals to contend with also, like most people.

I use a DMSA formula, but not every 4 hours, just in the evening before bed, with a little bit of fresh cilantro to boost (not required). I also use chlorella throughout the day, maybe 3-4 times, about 1/2 teaspoon or so, you can do more if you like, in a glass of water with a little bit of fiber thrown in.
That's my basic recipe for feeling fine and pretty normal every day, the DMSA at night (sometimes if I wake up at night I'll take a few more also, 25mg ea DMSA) and chlorella through the day. Drink plenty of water. Get plenty of fresh air and exercise. Eat greens. I take 2-3 days off from chelating each week, still do the chlorella w/fiber on those days. Lots of vitamins on days off (do not take vitamins with too much iron or copper), hyaluronic acid seems to help achy joints.

Get a colonic, next best after the DMPS. if you had a sore throat you need to clear your stomach of any mercury ASAP or it will leech from there for who knows how long.

Congratulations. I'm next, later this month...
