Well pregabalin with codeine definitely fucks you up.
Found it really hard to sleep after for some reason though. Odd since they're both downers.
Opioids may be "downers" but they are not hypnotics. They often physically sedate but make it paradoxically difficult to actually rest. If the body is not moving much at all but the levels of adenosine and cortisol are not at the level your brain associates with sleep a systemic action potential is generated. "Hypnic jerk" is the colloquial name for the result.
