WOW. Congratulations and what a great story!
There is an interesting wikipedia page on SAM-e, the SAM cycle, why you take it with B vitamins, methylation (presumably this is DNA methylation which is how genes are turned on and off).
Wiki points out that what you are doing has been shown to be a safe and effective treatment for depression in double blind clinical studies
Oral S-adenosylmethionine in depression: a randomized, double-blind... - PubMed - NCBI
There's a little warning at the end with a list of drugs that should not be taken with SAM-e + B vitamins and there is a caution about taking SAM-e with antidepressant meds.
