I am still on 2.5 pen and not ordering third pen for another week or so but I am planning on getting 2.5 if things stay the way they currently are. I have lost in the past couple of days after Christmas so I am still losing. I am getting reasonable suppression but I am also aware that I am making conscious decisions about food choices.
I am on this for a good year, maybe longer , and I am using this time to retrain my brain. My mindset has always been to stay on 2.5 for as long as possible.
Also, because of the constipation I have suffered, it worries me going stronger when I am losing on 2.5.
