Congrats on the 53hrs and your anxiety is more than likely due to all the other chemicals in analogs, hang in there. If it does become difficult this is good advice
Some people are able to switch over without too much of a problem others ween themselves over while finding out how vaping will work for them and others even swop over by accident where they tried it for kicks and actually end up preferring it. IMO there are 2 important things to keep in mind, one is dont pressure yourself unnecessarily and second dont give up on the vaping as there is a setup out there that will be just right for you.Lastly, and I almost don't want to say this, if you need an analog cigarette to get you through a particularly bad spot, do not beat yourself up for it. I went through three weeks and three different kinds of e cigs until I finally got my 510 and was able to get off cigs completely. Just stick with it find the juice that works for you and you'll be off those horrible things once and for all.
