Chigirl, Reread Bex's post! She was NOT suggesting you take 500mg 4 hourly!!
I was using a 3 day on 11 day off protocol of DMSA (100mg 3 x day) but after reading what Cutler had to say I took the book to my Dr who also likes to be up to date and it was decided that it certainly wouldn't do any harm to change where as not changing might do harm (according to Andy anyway). I used 50mg 4 hourly but some people go as low as 12.5mg.
I get very concerned re the anti Dr attitude on this forum anon. Not every Dr is a moron although I admit some are! I have a fantastic Dr who is busting her gut to help me and even if she did make a mistake I still believe I am far better off than some people on this forum who have no support and noone to bounce ideas off that have any chance of knowing what they are talking about. If nothing else she instills in me that I will get better and gives me the required optimism that many here lack.
