Are drugs making him act this way?

The percocet could absolutely be making him act completely different. My husband was put on darvocet (which is in the same family of drugs as percocet) several years ago for an infection in his foot and it messed with him so much he threatened suicide and accused me of cheating on him with my best friend (a guy). After the threatened suicide and after he got the meds out of his system he got rid of the pills. A couple years ago he broke his hand and they gave him Percocet and he was a complete a**hole the whole time he was on them without realizing it. We now know he CANNOT take anything ending in -cet (like percocet or darvocet).
