^You're touching upon a very important issue regarding Gabapentinoids. For those unaware, the Gabapentinoids are a class of drugs that include Phenibut, Gabapentin (Neurontin) and Pregabalin (Lyrica) among other drugs that are currently in development. We're still learning about these, as they are all fairly new compared to a lot of other commonly used substances. They appear to be very safe and non-toxic, even in extremely high dosages, but dependence, addiction and of course, withdrawal seem to be the major drawback.
I've been using these drugs (Pregabalin/Gabapentin) for a few years now. I discovered their utility for treating Opioid withdrawal and eventually grew to enjoy their effects independently. The thing is though, I use them like, twice a week. I've never been a daily user and have never understood (not judging) how people actually become dependent upon these drugs, as for myself, their effects wane at such a rate that they become practically useless after even just a few days of dosing.
For that reason, I don't have a lot of experience in dealing with the dependence/withdrawal issues of these drugs. They are said to be quite horrid and feature symptoms of both Opioid and Sedative/Hypnotic withdrawal, so that's clearly a big deal.
