^This. This this this. Except I might add the seizure threshold for it is actually only 200mg. So make sure to take something like a benzo or Gabapentin whilst taking it just to be on the safe side. Personally I have taken 1200mg within 4 hours and been fine, but I'm on both Klonopin & Gabapentin, and I'm not condoning that at all because it is very dangerous and the side effects get much worse at higher doses. The SNRI effects fucking suck, both for the high and the wd's, I hate tramadol but for some reason it keeps reeling me in.I've been addicted to tramadol for 7 years, beside other opioids it is my main one.
With tramadol the tricky part it's that it acts as a SNRI and an opioid too. so if you become dependent on it, you will experience both SNRI withdrawal and opioid withdrawal.
The SNRI withdrawal makes it very difficult for me, the anxiety and depression are pretty bad but the brain zaps and being on the verge of seizures is the worst.
You can give it a try to see if it keeps withdrawal at bay, don't exceed 400 mg to stay safe from having seizures
