Hate to be a killjoy, but in my limited experience, compared to benzos, G, or barbs, phenibut is 'a long fall for a short slide': it doesn't get you very high, but there can be, and often are, major side effects. If you have ANY kind of tolerance to downs, you'll be tempted to take a big (upwards of 2grams) dose, and then there's a pretty good risk, for a newbie, of nausea/vomiting and headache. Phenibut headaches are pretty damned awful, and a good way to ruin a night.
Use for more than 2-3 days in a row and you WILL experience rebound anxiety - booze helps, but if you wanted to get drunk, you wouldn't be taking phen in the first place. The sedation/euphoria, at its strongest, is like a very low dose benzo - and benzos are a lot less likely to cause nausea. And tolerance to phenibut builds ABSURDLY fast - for little benefit.
Of course, different compounds have different effects on different people - phenibut more than most - but at best, it's alright, and at worst a fucking nightmare. Avoid if you have access to G or pharms - if lacking such access, and in search of a down, start LOW (1g at most), and do not redose in same session, and never use more than twice a week. Drugs don't have to get you high in order for them to be nightmare, coming off - think 'Seroxat' - and phenibut withdrawal is worse, in some cases, than quitting opiates.
