like WillyB said... you're cravings are still there because you're probably not
vaping high enough nic cartridges, you should get some 18mg at least and see how you get on with those. As for flavors it's always personal preference, im kind of a 'fruity' (lol) guy myself.. i like the peach cobbler, banana, cola, dr pepper, RY4 (yum) and of course chocolate etc, if you like
tobacco type then 555 is good too, i haven't come across any flavors that taste like marl lights, i used to smoke those too so i know how hard it would be to find something close to that. Hang in there though it will take a few days to get used to your kit from the analogs but you'll be sorted once you get the right strength and flavor carts to your liking
Also don't forget you can post in the V4L subforum here if you need help, it's a very helpful place !
