Thank you for all the answers.
Ordered some bacopa, containing 450 mg 20% bacosides.
How long after my last dose will the withdrawal become apparent?
I've read 36 hours some other place, 24 hours others and 12 hours another place.
It's been almost 18 hours since my last dose, and I feel fine.
Depends how much was your last dose, phenibut half life is reported to be 5 hours but since you've been using it chronically the doses are accumulating.
you take 8g at 8AM today, at 8AM tomorrow you still have over 250mg (with supposed 5 hours half life), considering you've been doing that for many weeks you probably still have several grams in your body minus your last dose.
So yes 24 hours, 36 hours or maybe even 48 hours before first symptoms appear, it gives you enough time to prepare the withdrawal.
If they sell pyritinol (enhanced vitamin B6) OTC in your country you should take some (brands are Encephabol, Cerbon 6), it is known to reduce hangovers for alcohol, it's surely the same for phenibut or any other GABA agonist.
Magnesium should be taken too to appease glutamate surge, taurine is also potent in that domain. Ginkgo biloba has well is reported to reduce glutamate surge.
L-theanine for sedation and calmness without GABA agonism might be used as well.
As for Bacopa it's just for long-term chemical equilibrium, it usually take some weeks before it really acts however some users experience massive sedation or even drowsiness at first use. I did experience that but racetams cancelled out the effect.
