Ok so i am smoking 30mg juice from FSUSA out of an XHale O2. And it doing just fine for me, a little strong when i first started but now i like it alot. I am wondering if i get a new PV like a 510 will i need to adjust my nicotine level? I am thinking that 30mg is really really high and i dont want to be doing taking in more nicotine than when i was smoking analogs. Even though 30 is doing fine for me.
