What all were you taking and how much? We could try to answer the question a little better if we know more information.
Well, you could but it would be very uncomfortable. I feel that you should consult a Doctor or call a Methadone Clinic. They have meds that can help with w/d's. Don't be embarrased or shy, they understand and there are many more ppl that are in your shoes.
My best,
