Actually I titrated to 4mg last Sunday. And maybe it is just in my mind only, but got the feeling it was a severe boost. Started from 1mg and titrating 1mg every 3 weeks. Didn't feel much difference while increasing the dose before, but 4mg increase made it different. First of all, I have no cravings at all. It is Friday evening, and I ate much less, this week since Sunday. Beforhand I was getting slight cravings around Thursdays, but now not at all. Also was losing approx 1kg per week on the lower doses, this week I lost 1.7kg. Maybe it is coincidence, or a kind of placebo effect, but got a feeling there is something in the 4mg dose. And btw I do not have any crucial side effects since the very beginning on Reta and 4mg dose didn't change it. The only one I could name is a permanent constipation, but not as bad as I couldn't cope it. A lot of water and some fiber during the day helps enough...
