Yep. Doctor can't be sure it's the nic or caffeine. I went back to working days after doing school online on my schedule... so went from the cup of coffee for enjoyment to probably a pot in the morning just to keep myself functional. I'm drinking waaaaaaaay too much caffeine for sure. I'm also chain vaping. The doctor recommended I put the PV down if I can when I get any slight tingle, but not to mess with the nic level unless I'm sure I can without going back to smoking. My main plan is to attack the caffeine problem by either switching at noon to decaf, or mixing decaf and regular to get the overall level down. I'm also increasing water... which hopefully will eliminate a few giant cups of coffee.
For some reason this seems to happen when it's HOT out. If the temp is in the mid 70s, I'm fine. When it hits the upper 80s +, I seem to get this. The doctor said, move around, get the feet elevated, increase water, decrease caffeine, and stop caffeine and vape (if I can) when the tingling starts. I have decreased circulation in my foot anyway because I had a fracture in my ankle that didn't heal well and the tendon is rubbing over scar tissue. It swells and I can get tingling in my baby toe from that as well. This is about the same feeling except the whole foot on both sides. It's very slight, but enough that I noticed. It's also late at night after drinking coffee, sitting all day, and then chain vaping. The doctor thinks the nic I'm getting in 3mls of 12mg juice is probably not the main cause, it's just adding to what I'm doing to constrict my circulation throughout the day... and I'm noticing it at the time I'm vaping at night because it's compounding throughout the day.
