I Have Read That The Vitamin Vitadone Is Very Helpful

I have read that the vitamin Vitadone is very helpful for a person who is on methadone at a clinic and is serioisly decreasing his dosage each week, until he can be free from the drug!!
It helps with the symptoms of sweating, constipation, sugar cravings, swollen hands and legs and gives a boost in energy. Also may help in loosing weight !!
Can you please comment on this Vitamin and its helpfulness. I researched the Vitadone website and was pleased to see how much laboratory research was done. Truly a methadone user's bloodwork is not in the ranges of "healthy".
