Anyone have any experience with phenibut and know if it’s safe to take with 7

I impulsively bought a 60 pack of phenibut that’s coming today, I take 7 oh and smoke carts/weed all day everyday, I have taken x@ns before but that’s my only experience with this drug class. I’m probably going to toss most of them because I don’t want to risk becoming addicted, I’ll probably keep 10-15 and toss the rest so there’s a lesser chance of me becoming addicted because I already get bad wd from 7 but I’ve heard the withdrawal from this stuff is worse, I’m planning on only taking once a week max, what’s your experience with phenibut
