I agree with ricart, walk right now. You have done good otherwise, don't stop now. A month compared to the two years you already had clean? Cmon now. Walk my friend.
If you were clean and you have been on tram only a month I would take advantage and walk away.There will be very little in the way of withdrawal for that short of a run on it.You can do this just quit.There is no real advantage in tapering with this short of a time of use.Let it go another month and it will completely have it's hooks in you.That is what you should be scared of.
You need to find a local support group some people you can talk to about your problems if you are sick of the drugs you are ready for recovery it wont be easy but nothing worth having is easy and being clean is worth having. God bless.
