Congrats on the progress mate. Don't rush pushing down the nic levels(you're already gaining great benefits just being off the cancer sticks), 5-6 months is a solid point to drop your nic levels unless you're finding the things too sickly/harsh already. I personally stepped down in 6 month steps(wasn't counting, just roughly), things felt about right around that time as the nic levels got sickly and harsh around those points and the step down was a welcome adjustment(mostly on 3mg now, with a supplement of 12mg hits once in a while).
