2.5mg worked for roughly 5 of my first 8 weeks. One week I regained everything from the week before and two were flat, so I asked and went to 5mg in week 9. Since then I'm dropping 1.27kg (2.8lbs) weekly on 5mg, 8 weeks on each dose so far. I asked for more since appetite suppression was fading around day 4 or 5 of the week. Eight weeks into 5mg it now fades on the evening of day 6, which I just push through. If I keep losing I'll stay on 5mg, and I have basically no side effects there. I only swapped because effective loss stopped, though I still averaged 1.4lbs (0.63kg) weekly on 2.5mg. Over 16 weeks that adds to 28.5lbs (12.92kg). 76.5 lbs, or 34.7 kg, remain until my target of 180 lbs (about 81.6kg). I doubt I'll reach it, yet a goal was needed.
