“Tapering” off

I started my ZB journey at 2.5mg, and with each month have been moving up 2.5mg. I got to the point of 12.5mg and my body just cannot handle it. I let my doctor know and he suggested we start tapering off (also because I’m pretty much at my goal weight). So we decided that I’m going to do 10mg every other week. However, I’m worried that during the second week without the shot, I will start to gain my normal appetite back, and then the weight will come back. Is this something to be genuinely concerned about? I know it’s crazy to think that within a week I will gain a couple pounds back, but has anyone experienced this? Let me know!
