I did 4 weeks on 2.5mg and am about to enter my 3rd week on 5mg. Altogether I have lost a stone in weight but seem to be losing much slower on 5mg and am definitely feeling hungrier and peckish. Should I stay on 5mg or move to 7.5mg? I'm hoping that if I move to 7.5mg I will see more of a difference. I currently weigh 86kg.
