Third week binge eating again!

I’m on the third week of 2.5mg. Over the first two and a half weeks on 2.5 I lost half a stone, was feeling less hungry, more energy, no food noise, no binge eating, it was a miracle drug! On my third week now however, and the binge eating is back with a vengeance! I can’t stop thinking about food and my sugar cravings are back! I’ve gained most of the weight back and I feel like I’m going back to where I started. Anyone else had the same experience ? Does it get better again on 5mg?
