im on methadone maintenance, i go to a clinic everyday. i was using 7 bags of heroin a day, was shooting around 300mg oxy just to feel not sick, so my tolerance was around there. i was started on 30mg methadone, and increased 10mg every 3 days until i hit 80mg. the only "effects" i felt was eneergetic for about 3 hours then irritable after, i eventually made it to 130mg, it does not produce no high at all, it doesnt even make me energetic like it used to, only thing it did was kill all mental cravings for opiates and physical W/D symptoms, i began mixing benzos with methadone to try to achieve a high, which i didnt, i only felt the buzz from the benzos, nieve as i was, i didnt realize i can still die in my sleep even if id ont feel high or fucked up from methadone...this drug will kill you even i fu dont feel high, it stilll has strong CNS effects
