Been there, done that. Would I do it again, yes. As long as he does not have an adverse reaction (throwing up) then it will help in my opinion. If he goes for 5 days, the real results will bee seen 3-4 days after.

I wish there was a way I could give you my phone number without posting it here, I would be glad to answer any questions to the best of my ability. Maybe the moderator can do that for us somehow?
