Did you say what PG/VG you are using? If you are using juices with VG, are you aware PG lets through hit and flavor better? I mostly use 20% VG or less though I do drip a few thicker juices.
If you think you need more hit, the ways are more nicotine, more PG vs VG, more heat (may require a fatter ecig or a mod so you will have 450mah+ batteries and can use hotter LR cartomizer and atomizers)
If you are just getting cravings despite having good hit, try other juices. Remember to smell the vapor. Pay attention to which juices have taste/aroma/TH that makes you go ahhh and which leave you with an analog craving (and stop vaping juices like the latter for now). Some new vapers get analog cravings after vaping food flavors. Some get analog cravings because tobacco flavors remind them of cigarettes. Some can vape any flavors to start with. Figure out which you are.
If tobaccos generally satisfy you, try adding a bit of cocoa or chocolate eliquid to your cart/carto and see if that helps (most US cigs contain cocoa). Chocolate and cocoa in tobacco were part of ahhh for me and some others. And you can play other ways with tobacco flavors, adding vanilla, caramel, fruits like peach. Eventually that got me to the point where I could vape those flavors alone.
