Umm I hate to rain on your parade buddy but it took me 7-8 years before I was over my speed psychosis completely.
I'm not sure if you're dealing with the full blown psychosis from it, but it took only a year to develop and I lived with it for another 6 months using speed.
When I stopped I was still having hallucinations, and palpitations in the back of my head that would make my neck twitch. It affected my walk, my motor control, and being around people in general was extremely difficult due to all the twitching, paranoia and hallucinations that it caused.
I was in outpatient rehab for 2 months and had not spoke a single word because of the speed. And one day the counselor decided I had a pretty severe issue and got me to see my first psychiatrist ever. I was put on paxil and although it definitely sped up the process of getting over it, it definitely didn't stop it at all.
I was not buying speed as I was busted for having my own lab, so I also smoked and snorted on avg 4-5gms a day. At that rate it only took a year to completely lose my mind.
When I say it took 7-8 years to get over it, I mean thats when I had my last speed induced panic attack. I was still also getting residual peaks of paranoia, that wouldn't always turn into panic attacks, and what basically happened was over time the frequency just slowly and slowly decreased.
I remember after about year 3 even though I got over like 80% of the side effects, I still contemplated sucide often thinking I had permanent brain damage from the toxins in the speed. The other 20% slowly got better off the next 4-5 years.
Speed is a horrific fucking drug that triggers so much dopamine in your brain the dopamine beings to behave like ammonia (the amine in dopamine is essentially an ammonia branch). Dopamine even in little amounts has the ability to corrode and kill off brain cells, in large amounts it can also damage blood vessels in your brain. To add to that corrosive property of dopamine (alcohol does NOT release even close to the amount of dopamine that speed does)
is that most speed is not fractionally purified properly in labs, so lye, iodine, and phosphorous often contaminates it. If you are smoking speed those lye vapors can cause SERIOUS damage to your brain.
If you just take it orally its not as bad. Unfortunately I was doing both however.
I'd venture to say if you were just snorting or injecting speed, you will be over it much quicker. If you ever smoked it however, its is MUCH MUCH worse. Injecting and snorting will somewhat prevent the toxins from going straight to your head, smoking it keeps the toxins in a vapor state which allows them to cause a lot more harm to your brain. I remember several times taking my morning hit and vomiting all over the place than falling to the floor. I was prob as bad as bad gets when it comes to smoking it. So my case is definitely more on the extreme side.
By I'd say once you get done and over speed, use ANYTHING IN THE WORLD you'd like, just DO NOT ever go back to speed.
I still can't take ephedrine today because I start twitching and shaking terribly from it, and almost any stimulant besides coffee has similar effects. So my stimulant days are long over thanks to speed. Opiate although physically addictive, do not cause brain damage like speed. I'm not saying go use opiates, just realize that speed is very much its own demon and really a terrible drug to be hooked on. Its odd that I had such a hard on for stimulants back in the day but 9-10 years later slowly feel into opiates. I believe I took such a liking to opiates in the first place because they relieved me so much from the speed induced bullshit. But the bad thing now is when I wd from opiates, I get particularly bad symptoms from too much adrenaline. My blood pressure always goes hypertensive in wds and insomnia doesn't seem to get better for weeks and weeks. When most people will get over that stuff relatively soon.
G/luck!!! And if you need to get on an ssri the one that wound up working best for me was Lexapro, not Paxil or Zoloft. Zoloft is a stimulant, which actually made my panic attacks more frequent. Paxil worked somewhat, but Lex was just so much cleaner and more affective for my long term sideeffects.
