I used kratom extracts daily for years and quit no problem. It was kinda like quitting coffee, very tired, didn't want to work, didnt give a shit, but ephedrine and a caffeine helped me through days, with etizolam every other night with pretty much no side effects, and all "withdrawal" gone in 5 days.
Then I got into tramadol for 3 months. I was up to minimum of 300mg a day. Went on a bender where I did about 800mg per day, for 7 straight days, along with etizolam to raise my seizure threshold so I could keep chasing the high. When I quit I contemplated suicide. It was the worst I ever felt. The derealization was insane. I didn't know what I was, who I was, or where I was. I felt like life was an illusion. Terrible brain zaps, auditory hallucination, no appetite, and my vision was fucked up for a long time.
It's funny because now I'll go on 5-7 days oxy binges where I'll do only maybe 30-80mg of oxy in a day depending on how much spare cash I have. The withdrawal isn't too terrible, but I guess because my first taste of withdrawal was so bad, I usually get through them no problem with a few teaspoons of kratom a day. I feel like no withdrawal can ever touch my tramadol withdrawal except for large methadone dose withdrawal, or large dose benzo withdrawal. Mid range opiate withdrawals are nothing to me now, I get over them quickly, and with no problem. People at work can't tell I'm sick, neither can my family.
I warn anyone who uses tramadol about slowly weaning off and not cold turkeying. If there is a hell, tramadol withdrawal is what it feels like. I read somewhere that tramadol affects Opioid, Gaba, Serotonin, Dopamine, Norepinphrine, and a few other chemicals/receptors in your brain so its like coming off multiple drugs at once. The minor relaxation from tramadol is not worth the withdrawal, that I've heard can last up to 6 months (mine was about 2 weeks). Doctors need to stop handing these things out like candy, many of the doctors and shrinks i've been to still believe tramadol is non-addictive. I'd kick an 80mg oxy habit over a 400+mg tram habit any day.
