Hey Mum, Good on ya fur the quit. I can sorta relate, smoked tobacco for 52 years, my heart attack was 25 years ago. I'd say I'm a pro at paranoia. Everybody else's advice is great. . .do any or all of it you choose. Myself, I did what I did because Chicken Little went running by my house shouting, "your government might shut down vaping". I've 2 gallons of VG, more than a gross of CE2 XL steel and clear carto's, (that I'll stick in a syringe tube mod), several 180 mL bottles of hunnert proof nic, same for my Cinnamon flavoring, and order my Big Batts by the half dozen. Looking to order 20 Clear Shorty drip tips as I type this. I don't know what to tell ya Mum, I have no experience with your PV. I now vape ProVari, and never have any trouble getting 50/50 or > % VG juice to wick. My, (natural), motion of tipping my Pro to the horizontal position when taking a hit, automatically feeds juice to the coil. Hope ya get it figured out. I haven't had a cigarette in so long now, if my PV crapped out. . .I'd prolly just drum my fingers and smell a cinnamon stick. Good luck.
Cheers,
