If its not a private methadone clinic, most likely the intake process can take weeks or even months. I have heard private clinics are a lot easier to get into, but you pay for that... When a close friend was in a similar situation, the clinic counselor actually told him to score whatever he needed until he could do the intake. Crazy,huh? I know that there are a couple people selling methadone pills on Sr market, i think, you might want to hit them up, but for your situation, methadone or suboxone is the best bet, last the longest, but make sure you are off the subs before your intake. This is a tough spot, in a pinch, go get a ton of lopedermine, and when they say take 4 take 10 wait and then take more as needed. that should take the edge off, also if you can get clonodine, that will help. if you are sick and have no options, then go to the ER, they will give you lope, clonodine and trazadone and maybe some xanax.. but, then its in your records.. Go easy on what you have until you know what and when you are going to do it....I have had methadone last me 3-4 days before WD came back.... But remember, methadone is much more difficult to come off of than pain killlers, etc. instead of weaning over a couple weeks, methadone can take months or more. same with subs... so, you may want to get on a fast acting opiate and taper yourself with some friends help (to control it and monitor you). take plenty of fluids......
