At one point I was on 15mg for a few months and lost 6 stone in total. I had titrated down to 2.5mg and then had to come off abruptly after Xmas due to money. In that time I gained a stone and I believe its because if the abrupt end, I had always planned a methodical exit and old habits came in too fast because I had no plan. Anyway, thankfully back on 2.5mg but its not as effective as first time around (or maybe first time arpund was part motivation/placebo).
After week 1, why couldn't I go to 3.75mg or 5mg? I wouldn't go any higher until 4 weeks is up, if even needed
