Carlyawesome, welcome to the discussion.
I'm about the same... I was a 1 pack a day Marlboro Light smoker (either shorts of 100s, didn't matter). I use 24mg liquid, and been off analogs for almost two weeks.
I'm using liquid from Pink Spot (my local eCig shop sells them) and Backwoods Brew. I believe these are a good portion of VG versus PG.... on Pink Spot, it can be anywhere from 70/30 VG/PG to 50/50 from what I understand. I've had no wicking issues on any juice so far.
I do occasionally get analog cravings even on 24mg. I just hit it hard until they subside using the techniques on the beginner's tutorial on this site (hold vapor in mouth, inhale, exhale slowly through nose). Vapor is different than smoke, it takes some time for the nicotine to get into your bloodstream. This can be a learning curve when you're at work on a "smoke break" and are used to having an analog and getting that quick nicotine fix. I find it can take 5 to 10 minutes before I get a satiated feeling if I haven't vaped in a few hours.
Also, I found that getting a liquid with a very strong smoky flavor and throat hit helps (one that comes to mind is Pink Spot Honey Cured Tobacco, my first juice, which has a super hard TH for me).
Finally, you'll be happy with your eGo-C... it is a good quality base system with a world of options. Everybody is different, and what works well for you may not for others. That's the fun... finding out what works well for YOU.
