I have taken about 100mgs every day for about 5 days before today
Sooo.. How did you end up running low early if you were taking less than normal?
You said you were taking 120 for 2 years no?
It doesn't really matter, it's just to get a rough idea how long you probably have till withdrawal, I'd need to also know how much you're usually dependent on.
Unfortunately, assuming you're dependent on 120mg. And have taken 100mg roughly every 24 hours for the past 5 days, and then today took 25mg. I'd estimate you have about 30 hours till the start of physically noticeable withdrawal.
You'll might start feeling kinda meh well before then, but it shouldn't be too bad for about 24-30 hours from now assuming you just took the 25mg.
I'm sorry but I don't see you getting through this without a fair bit of withdrawal
I can't see any way to stretch the remaining 50mg into enough to avoid it by itself. I figure each remaining 10mg of the 50mg is only gonna delay withdrawal by about 5 hours at best.
I recommend waiting as long as possible and taking as little as possible to stave off the withdrawal when it comes.
Otherwise you could wait as long as you can hold out, and take a bit larger of a dose, then wait again.
Good luck man I really mean it. I hope I'm wrong. 30 hours is based on my own system for tracking my own methadone use, your body might take longer to go into withdrawal than mine.
If I were you though I'd recommend having some loperamide or something on hand to help get through it if it gets bad.
Try not to beat yourself up too much. You can't change the past, and a hell of a lot of us have wound up screwing ourselves like this. I know I can't even begin to tell you how many times I've called myself an idiot for using more drugs than I should.
