Theres no comparison between Gabapentin and Pregabalin! Pregabalin is much stronger and feels a lot more pleasurable! I wouldn't mix them theres no point as gabapentin might hinder pregabalin's effects a little, just stick with Pregabalin.
Oxycodone and Pregabalin is a very good combo if u get the dosing right! I'd take the Pregabalin first and wait till it kicks in then take the Oxy, if u take them together the Oxy will kick in well before the Pregabalin.
