You kinda have to try to actually get it.It's pretty damn tedious to get it in the first place.
It may have been a bug, but I lost it by taking the maternity leave in the nursery for like 80 days.
Just don't do venom again or you'll relapse.
Addiction - maybe, when PC becomes a Venom Slut it's supposed to be permanent. Definitely looks like a bug to me, should probably report it.Well taking maternity leave was spending much time sitting in nursery so if venom addition lvl can drop without more nasty side effects simply flow of time ingame can help to getting rid of venom slut.
