Are you aware you can use cartos from Vapor4Life, SmokelessImage Volt, Bloogplanet MaxxFusion, Halocigs G6?
You could try my fave Vapor4Life juice - WOWbacco (cocoa tobacco) or if you are a menthol smoker the WOWboy is the same with a bit of mint added. Their WOW tobacco sampler contains both. Sharp-edged hit for its nicotine level, especially in the Vapor4Life WOW cartos. And cocoa is an ingredient in most popular US cigs. Some people make their own cocoa tobaccos by adding chocolate or cocoa eliquid to their fave tobacco eliquid.
Or for a nutty somewhat pungent tobacco eliquid that reminds me and many others of a freshly opened pack - try Desert Ship from FreedomSmokeUSA and I recommend 80PG/20VG in cartos
Pay attention to how well different juices satisfy you. Stick with juices that have flavor and/or aroma and TH that relaxes you. For now, stay away from any flavors that leave you craving an analog. For some new vapers non-tobacco flavors leave them craving an analog. For some, tobacco flavors do that. And some can vape anything right away.
Remember to smell the vapor.
Your mornings and bedtimes may be easier with a 3rd battery to leave set up all night, vapable to the minute you go to bed, or if you get up in the night, or first thing when you wake up.
