I'm only a few weeks in, but this is the path that I followed as well. Week one was .5, week two was 1, three was 1.5. I experienced appetite suppression from week 1, but it trails off by day 5 or 6 as mentioned above. My goal in starting small and making small increases was to titrate up and better visibility into dosing if any negative side effects creep in. Currently, I am sticking to a 7 day cycle, and I am hoping once I get up to a little higher dose or have a higher therapeutic level that the suppression will stretch the whole week.
If it hasn't improved after a month or two in the higher dose range, I may look at splitting the dose and doing twice a week, but I want to give it an earnest shot at working before going that route.
