hi diane : sorry for your hell , I was on 5 diffrent types of antidepressants over a one year period and know what you are going through ,it is shear hell , then to top it off with mercury poisoning "what a mess" my only advise is that you take it very slowly on the withdrawl of the antidepressants ,that is a battle in its self , I went cold turkey with mine and do not recomend it to any one ,and can be very dangerous, as for the chelation you may want to lower the dosage of dmsa and ala ,chelation is good but the body can only handle so much before it will cause problems like you are seeing ( hope this helps )
