I just wanted to add something, I didn't realize this before.
I dosed the phenibut while I was on 300mg of Tramadol (Don't worry, they're the 50mg non-APAP ones) (for harm reduction purposes I will note that this dose could cause seizures in some people so I don't recommend it -- I have a high opi tolerance and people react differently to Tramadol so start low as with any new drug you try). Perhaps the Tramadol significantly amplified the Phenibut? The SSRI? The SNRI? The M1 opioid metabolite O-Desmo-something?
I don't plan to repeat this Phenibut use for awhile. I am going to titrate to lower doses just to achieve long lasting anxiolytic effects, instead of feeling like I'm on a heavy benzo for 1-2 days then sleeping 20 hours without waking up once, and even after 20 hours you must force yourself to get out of bed. It's really not a fun feeling, that.
I will try dosing it sometime without the Tramadol and post my results. Maybe there is an unknown interaction here (I could find nothing in FDA's database about interactions aside from mixture of depressants -- GABA agonist and opioid -- the M1 metabolite of Tramadol).
Anyone else mix Phenibut with Tramadol before? Did you experience similar amplification to the point of drunkenness/benzoed/stupefied feeling for an extended period of time followed by an unhealthy amount of sleep?
The form of the Phenibut I took was a bulk powder. Two heaping teaspoons dissolved fully into water. Even though It's FDA approved for human consumption I assume it's still considered sourcing to mention the source, so I won't.
EDIT: I admit to not reading much about GABA agonists, the OTC ones, or unscheduled ones, but wouldn't Phenibut cause the same physical dependency that benzodiazepines, barbituates, and other GABA drugs would cause if dosed daily for months? Wouldn't this cause the similar withdrawal -- seizures, grand mal seizures, or worse?
I'm not complaining about the FDA making this OTC but certainly there should be warnings if it causes such heavy intoxication. I'm against the concept of drug scheduling personally.
