Read the work of Dr's Kenneth Blum and Kathleen Desmaisons
and look at http://www.radiantrecovery.com
From you medical history i think this will really help you.
It takes effort, but there's a support forum on the link which really helps.
It's no easy but you can get stable and healthy and learn how to look after yourself for the rest of your life.
i wish I'd known about this 20 years ago!
