I changed from MJ to W a couple of months ago due to the price increase and have been on 1mg so far, felt like I need to increase my dose so have got a 1.7 for my jab today and would like to know if anyone has done click counting to increase the dose more gradually and, if so will the pen allow me to use it more than 4 times or will it lock up after 4 goes even if there's liquid left in it? I still have lots of spare needles from being on MJ for the best part of a year.
