Your story sounds much like mine - I took up vaping when I didn't have access to Vyvanse (between jobs). It helps, but I found I liked it enough to continue. These days I use 6mg/ml juice, and use ~5ml per day on average. I've not found any real negative effects after about a year. I go increase and decrease my intake periodically, and the worst effect I've had is a "stuffy" feeling in the morning when I hadn't vaped anything the evening before. Even that doesn't seem to happen when I'm in a period of decreased usage; I've stopped for a day or two before and didn't really notice. FWIW, nicotine does work as a cognitive stimulant, at least for me. It's nowhere near as powerful as Vyvanse, but it's effective enough that it helps me "get back in the flow" when I'm not interested in something but need to get it done.
