I used to wake up in the mornings and smoke 3 - 5 cigs just to get going. Originally started vaping at 18 mg and did not sleep well or get enough to vape in the morning - chain vaped til noon. So now vaping 24 mg or 18 mg in first thing in the morning, switching to 18 mg before lunch, and down to 11 mg at about 4 p.m. The PV is on the night stand so I can take a hit or two and never get up (make myself lay there). I may need to try vaping 11 mg by after lunch, but working on this arrangement now. So far so good - sleeping is improving, resting better. Would like to hear how you do.
