Anybody ever have this problem? I use 3mg nic on my mod. I've got an eleaf istick power and use a tfv8 baby beast. I run it at 65w, the place I get my ejuice from makes their juice fresh as they don't steep it and gives me a nice "rush" but after a few days of using it that "rush" goes away and my brain seems to crave it more and I don't feel that calming sensation anymore. It feels like I'm not getting enough or something. Is this normal?
