You mentioned alcoholism in your first post. There is no medical cure for this. Medical supervision is often desirable during detox for the reason that withdrawals can be dangerous on some cases.
This will get you clear of the booze, but it will not keep you sober. It is one thing to stop, I have done it a thousand times, but quite another to stay stopped. If you are an alcoholic of my type, even after a long period of abstinence, if you should pick up you are guaranteed to lose control again.
The suggestion made earlier to use the time you have tocheck out the AA program for permanent recovery is a good one.
