Welcome to the forum suzy1q. I think all who are reading you are pulling for you to stay off cigarettes successfully.
I agree with ShowMeTwice that if you feel like you're "dying for" anything, you may need to raise your nic level. I'm not sure, when you say 0% and 3%, exactly what you mean. Is that really two bottles you're using, one with zero nic, the other with 30 mg per ml. (3%), and are you alternating them or mixing them for an average of 1.5% or 15 mg. per ml?
I hope this will be helpful to you. When I was a new vaper, I found the eliquid flavors with "cigar" and "pipe" names actually tasted more like cigarettes than the ones labeled as "cigarette" flavors. ECBlend Cuban Gold was the one that really tasted to me like cigarettes. It's supposed to be a cigar flavor, but tastes more like cigs, and no nastiness, very smooth. Also there were tea flavors that tasted more like cigarettes than so called cigarette flavors.
As many vapers progress, they no longer want anything that approximates a cigarette flavor, and start to explore things like chocolate, fruits, coffee flavors, nutty flavors and so forth. There are a zillion possibilities. After about a year of trying flavors I settled on clove.
Each new vaper's journey is individual and your own. I wish you success and good health.
