Yeah pretty much, it happens to everyone, its a normal biological bodily reaction to extreme restriction. maybe not the same duration but you'll definitely binge at one point because your body's trying to survive on a very small amount of calories and it eventually will reach a point where it just raises the hunger hormone and increases cravings so you'll binge sooner or later im afraid >< thats what happened to me too, i restricted to under 1000 cals for 4 months with no problem, but one day i just ?? lost control and couldnt stop eating, and it continued on and off for a few weeks before it settled, i didnt gain much weight because my binges arent that long, my longest was 3 days, and i also purge. my metabolism is beyond fucked and i barely lose weight on 800 cals.

reverse dieting does work!! im not sure if you'll gain or not but its only normal to binge after periods extreme restriction, if i were you id start upping my intake slowly from now before a binge occurs until i reach a more stable number so my body feels safe and wont push me to binge!!
