The first three weeks of vaping, looking back, I was probably doing too much nic. Always seemed to have way too much energy and a LOT of trouble sleeping. Then I discovered other flavors and found V8p Bar's Dark Side and got it at a lower nic level. The first bottle or so was a nice, spot-on peanut butter with chocolate overtones. That really satisfied my craving for sweets after dinner for a long time. I ended up losing about 15 pounds the first two months. Now I have other flavors that I rotate but I still come back to Dark Side most evenings. It does curb my appetite and I get my "sweet" fix with it.
