I wonder if it was the VG of the 50/50 juice that bothered you then. Might be worth trying an 80/20 PG/VG juice. What equipment were you using? Perhaps vaping isn't for you but if you want to see if the problems you have had can be explained and worked through, maybe it would be worth letting the Apes guide you a bit. Whatever suits you, of course.
Hi i started on 50/50 then went to VG with no nic just to try it.
