if you feel withdrawl, typically your ready for a suboxone dose, at the worst u may feel very minimal precip WD...which will go away within 1 or 2 hrs (if ur taking regular opiates, except methadone) i just recently went thru one HELL OF A RECIP WD EXPERIENCE. i was on Methadone for 1 year, got kicked out the clinic, and they slowly detoxed me, i got down to 20mgs, very sick cuz i was on 130, so i was eating 500mg morphine a day on top of the 20mg of meth, and occasionally taking extrra meth pills off the street..i made the choice to call my former suboxone doctor, and we agreed to do a procedure in his private office, so saturday i went in for this "procedure" mind u, i stopped methadone 48hrs in advance, and took my last morphine 24hrs before my sub appt..on saturday i woke up and felt sort of sick, i knew in my head i was not ready to switch to suboxone, even though i felt sick (methadone was the issue, they reccommend 4-5 days off of it, then switching, but they say u got ot be down to atleast 40mg meth to switch). anyways this procedure me and my doctor talked about was going into his office, forcing myself into precip, to get all the methadone and morphine off my receptors..so i walk into his office, he directs me to fill my suboxone at the pharmacy and return, indeed i did. he took me to a back room with a bed, and he said "u dont even know what ur up against, i told u this wasnt a good idea, but if ur serious about getting clean immediately ill do this for you". so i lay on the bed, and took a half a sub (4mg) 20 mins later nothing happpen..so i thought i would be fine since i felt withdrawl from opiates i was using..i figured fuck it, whats a little bit of diarrea and nausea/vomiting for a few hours? boy the physical part of the precip WD, was a cake walk compared to the mental part.,..i felt like i was on a BAD ACID TRIP/combined with the feeling coming down from crack, i was crying over every little thought, it was like nighmare on elm st..then the doctor forced 16 more mgs under my tongue, at this point i was flopping like a fish on the bed, hot sweats cold sweats, the MOST HORRID restless leg feeling, i swear i never shit so much in my life..by me crying so hard i ended puking, as i lay on the bed, with my life passing me by with guilt and shame, and thoughts of death, cemetaries, morgues, and a failure...shaking, 3 hourss had passed, which felt like days, the doctor took my blood pressure, and said im safe to go home and deal with the precip WD ( i thought i would only be in precip WD for 12 hours at the MAX), little do i know, when i got home, i still was flopping like a fish, the peak of the worst, went away, i now felt like i was going thru severe heroin withdrawl (which in precip WD, that feeling is the end of the Precip) being in full Precip WD, is like opana or heroin Withdrawl 100x, literally..i was in Precip WD for literally 3 days..the next 3 weeks after i just felt weak, even taking 3 subs a day, i still get leg cramps, the yawning, teary eyed classic opiate withdrawl feeling..precip WD is NO JOKE....but if ur just a normal opiate user, and u feel mild WD and feel sick enough, its safe to try taking 2mg-4mg to see if u feel better, and if u do go thru precip, it will be real mild for 1-2 hours..now taking suboxone while ur still high on heroin, or clearly not sick at all can def be painful for 10 hours...but methadone coming off of precip WD, i wouldnt wish on my worst enemy..i swear if i had a gun i would of shot myself in the head...thats why the doctor mandated me have a family support thru the whole precip Wd..sorry for rambling off topic...typically, wait 24hrs till u take a suboxone to avoid precip WD, or take a small dose if ur feel withdrawl at all, even if its mild, chances are it iwll be a bit uncomfy for 1-2hrs..man what a rollercoaster ride that was....rule of thumb, only take a sub when u truely feel withdrawl, dont let ur mind think ur sick..just wait for the classic symptoms..yawning eveyr minute, runny nose, diarrea, resltess leg..i been thru precip WD with heroin, it only lasted 1-2hrs, i went thru it cause i wasnt in full withdrawl, but after 2 hrs i felt better, idk this is my body, and experence...sorry for rambling off topic..im on addys and just, well fuked lol
