When I was at my worst(right before I prayed, and Prayed, and prayed somemore about if it was the right thing to get on at a Methadone Clinic,at worse I used around 8-12 K4's shot a day, and sometimes spending 150-250 bucks in one day, and consuming all that oxycodone and Hydromorphone is less than 24 hours. I was using WAY less than you, and honestly, these 9 months have been strange but, Ive somewhat had my life back. I can actually keep money for really as long as I want before I spend it where before methadone I made 1300 a week at my job and was still broke(talk about discouraging)

Methadone Matienance is well, somethings I am SO THANKFUL that I got some decent stability back with Methadone, but at the same time, my tolorence in un-godly and only good dope or Oxy/Hydromorphone IV will even give me an itch. For the amount your using, thats not feesable for ever bro. I'f I had a choice between 60-80mg of methadone a day or be shooting 4 grams of raw, it would be way wiser to be on methadone for as mark renton says to keep your life!
Anyways, I wouldnt decide overnight. Sometimes with methadone, its best to have a longterm plan. And you have to weight the Drive/Miles round trip, price of clinic(private or Public(Veterans Affairs), compared to coppin on the streets and everything that goes along with that. I dislike that I AM ADDICTED to methadone, but, its alot better life than shooting opiods IMO.....just being real
