On Monday I have to have a minor surgery. This means no water after midnight on Sunday. I have a one hour drive with no traffic. Unfortunately I'll be in rush hour traffic in Chicago, this can easily take an additional hour. I know the importance of drinking lots of water with vaping. I also know there is NO WAY I'm going to even try to not vape before my surgery. I'm currently vaping PG. Should I try to get a 100% VG this weekend? Or just keep vaping the PG and not worry about it.
