i know the methadone/sub route seems like a saving grace for you - but to be honest, if you can't use loperamide to taper off opiates then Methadone/Sub won't be any easier. . . they aren't suppose to get you high - it seems like even when you have the lope you do enough to feel high, the methadone/sub is given to you in low doses so you don't get high, it's to make you feel normal, and a dose of Loperamide will do the same thing ( i'm not talking herioc doses like 200-400mg )
as low as 20-80g of lope has the same effect as methadone/sub - and last a bit longer before withdrawals kick in, i've known i.v herion users who used 30 lopes every day and got clean. . . i really don't think methadone would help you at all, frankly i think it'd make it worse - since you are already combining loperamide, tianeptine, phenibut. . . i can only imagine if you started mixing Methadone/Suboxone into that. . . (granted methadone/suboxone would be safer, but loperamide is safe too if not taken in huge doses, and if you can't control taking small doses of loperamide, i fear for adding anything else to the mix )
i think the hardest part of getting clean is - you can try to catch a buzz, or just avoid withdrawal . . . or get CLEAN - and at this moment i still feel your priority is getting a buzz ( hell, aren't we all? ) - because you are taking way too much loperamide, you're taking it to get high, not avoid withdrawals...
remember, feeling normal and not high, is better than withdrawing/being homeless!
you can do this - because eventually, you'll get to the point were you won't be able to get high. . . you'll sky rocket your tolerance so high, you'll never get high again, you'll just fiend off withdrawals. . . and it seems you're pretty much there thanks to the Lope/Tianeptine/U-7/etc. . .
i already mentioned lyrica, i don't think it'd help you at all - the phenibut is greatly effecting your GABAB and very very slightly your GABAA - Lyrica would have minimal effects on you - beyond wasting more money :O !
the Lope IS CARRYING YOU for two days. . . it's just now your tolerance is so high you aren't feeling high, you are NOT in withdrawals already from it. . . please do no redose
a lot of this is mental. . . remember, i know it sucks - you wan't to get high but now you're brain has such a high tolerance to everything you can barely manage to feel normal..
hang in there!
