I have read this is a mineral problem. I think all health problems are a mineral inbalance of sorts.
I have seen people flip and become another and later not know they did, as long as they are on medication they seem to live a normal life. Naturally this drug does not address the issues that cause the problem.
I would suggest you stay on your drugs and as you correct the diet and cleanse the body, odds are you can be weaned off the drug.
