Okay so far well since methadone stays so long in your body it accumulates this means that with the first dose, when opiate tolerant, of 30 mg you dont get the full relief from that dose and accumulation is max passed day 6 so only then a higher dose i safe except for very strong opiate habits then daily or every other day 10mg added.
Methadone is very potent and then to think that from the methadone we get only half is able to activate the mu receptors so we call our methadone a racemic mix and only in Germany they still use the working part alone, but since its too costly to make the acting part alone by now most Germans get racemic methadone too this costs a few cents per dose the other methadone has polamidon brandname this i used a few times only to find out that half of the stronger methadone covers for the racemic mix.
Good question Caty about when you will feel oxy again i can tell you that when i had 140 of the 40mg oxycontins, who didnt act with the 'done regardless of the oxy dose so i waited three days and only then i started to feel sickish so i thought yesss lets drop some of the oxy and i took an insane amount i wont name people wouldn't believe me and it didn't work at all not even slightly i remember that ages ago i was at only 50mg,for me, and decided to smoke some heroin and still the methadone messed up in getting a buzz so the advise i can give you is to get to around 30mg's then you will feel oxy again.
Going down from 75 mg to the named 30mg is easy you can start with taking 10mg less at once, but since 'done accumulates in about six days taking it also losing some mg's takes some days before you can say the reduction is not too big. You can also go to say 40-50mg instantly then you should feel an oxy buzz like i noticed from friends, but i have to add that those friends never got higher then 50mg of'done so better would be to go slow and to wait until your body is fully used to say 40mg methadone and then for sure an oxy buzz could be yours.
Keep in mind that my advises are for somebody opiate tolerant.
Ofcourse its better when you stay on methadone else the effort you took from a pre existing habit was useless, but i do understand your desire for an opiate buzz i wished i could feel oxy or morphine, which is useless so i take rather big doses of methadone like 300mg+, pregabalin, seroquel (still dont know why i get that one) some benzo and 2 hours later when this complete mix works i smoke some cannabis and then its like a button gets turned, because everything now works fully. This is NEVER to be repeated by whomever else.
Well what's more about methadone strangely some people on doses like 90 or even 110 mg claim to feel a heroin buzz, but that's in theory impossible with the weak heroin we have here in the Netherlands it goes trough too many hands who all throw some caffein in and what's left is heroin with maybe 25% purity and that's a high estimation.
We have free heroin here and that stuff is truly great after i could use a little bit somebody smuggled out, but getting in is hard and having to show up twice daily minimally sucks still maybe this is the way i can get rid of methadone i take for almost 30 years already.
Well so far i hope i made this reply readeble.
Best regards Me.
