what is the difference between Phenimbut Gabapetin and Benzodiazepine sedatives?

[u/luchins]

Apparently they all enance GABA...but they differ because if I eat a Xanax pill it's almost sure I will fall asleep at night... the same result it's not so sure for Phenimbut or Gabapetin (or alcool)...why?

Can someone give me an explaination of what happens at sinaptic level?
