That sounds just about like my last oxy withdrawal. + puking. lots of puking.
I never puke, it's always the other end. Anyways... my experiences quitting various substances cold turkey:
Methadone #1: You Cold Turkey this shit and you are in for a hell-storm. Undeniable and chronic muscle spasms, diarrhea, beyond excessive sweating, extreme dysphoria, extreme insomnia, extreme fatigue, your entire skin feels like the tip of a penis scraping against sand-paper (supposing you aren't into that), the list goes on. I even feinted twice. The WD is bad enough; it has one of the longest half-lives in the opiate world. Plus when WDing from 'done, as I did, most people are going cold turkey after potentially multi-year daily consumption. There is no "out of stock" at the MMT clinics.
Oxycodone #2: After a 160mg a day OxyContin habit of two years quitting cold turkey obviously included the usual: diarrhea, excessive sweating, insomnia, fatigue, anxiety, loss of appetite... but most of all I remember the
pain. It felt as if the very marrow of my bones had been replaced with broken glass. This one physically hurt the worst. But due to the duration being half that of Methadone I have to rank it mi número dos.
Heroin #3: Quitting heroin after two years, my daily consumption and ROA being: 1 gram if IV'd (the town I was living in coupled with no car and a shared apartment with my father made it tough to get a steady supply of clean/new syringes); 2 grams if smoked. I should note this was BTH--many more psychoactive alkaloids, however consistently lower in potency than ECP or CW. My muscles weren't twitching like they did from 'done WD, but there was a distinct fogginess of head coupled with the usual anxiety, depression, flu symptoms, insomnia, RLS, displeasure at any tactile function... Obviously it fucking sucks. But because it didn't last as long as the 'done WD, didn't hurt as bad as the OC WD, I rank H 3rd.
Opiate WDs comprise the absolute worst experiences of my life. What I'm real scared of are combined Opiate/Benzo WDs. I won't lie to you all and myself, I'm a complete benzo addict. Yet even at high doses: 6-8mg clonazepam daily for weeks on end, abrupt cessation hasn't caused me quite the level of grief as Opiate WD. Possibly because I generally have opiates + cannabis when WDing from benzos. I don't know.
Benzo WDs seem to be very similar to Opiate WDs: less pain, but more anxiety and insomnia obviously... the panic attacks are hell... and the risk of seizures (luckily I've only had a minor one once from benzo WD)... plus the actual threat of death to an otherwise healthy body... I'm scared. Maybe Benzo WD is the worst and I just haven't felt it's full effects yet.
Stimulant WD: Walk in the park. Less energy, increased appetite, foggy mind. That's literally it. And that was after 9 straight months of daily crystal meth usage. I have heard of people experiencing nasty brain zaps and headaches, but I dunno. Always been easy for me, let me say though I recognize we all have different brain chemistry.
GHB: After two straight weeks of a GHB binge (plus Bupe, Kpins, Meth, Cannabis) abrupt cessation of the GHB brought on intense cravings and what most probably was a small seizure. I already carry enough proverbial monkey's on my back, the experience was enough to motivate me to back off for a while.
Cigarettes WDs: Not bad as long as you don't get angry or anxious. Or Drunk.
Marijuana WDs: Bullshit. Smoked a quantity of quality herbs daily for over 6 years. Many abrupt cessations, of varying duration (some lasting as long as a year) have never aroused any problems for me other than decreased appetite and boredom--which shouldn't be confused with absolute dysphoria/hopelessness. Stop complaining. If you think this drug is addicting you could get addicted to moth balls.
