Hi and welcome to ECF, yes, getting to know all about ecigs often leads to this uncontrollable desire to buy some. Congrats on 3 years. The good news is, after a while , well, it can often slow a bit. I will say, it did for me, but some seem to have more stamina than others.
The also good news is whichever way it goes, you'll have lots of fun things to vape. Welcome aboard.
