In my experiences, methadone is at least, if not more, addictive than vicodins plus the withdrawals seem much worse and more drawn out. In smaller quantities, methadone
gave me tons of energy but when you're talking about taking wafers
(40 mg) at a time, it will make you pass out. I actually switched to vicodin just to help with methadone withdrawals cuz I thought nothing could be worse. I was only up to about 1/2 wafer a day, so I can't imagine what would be for someone taking 8x that.
