Try to incorporate some healthier eating as mentioned above higher protein, low carb meals as they fill you up better and prevent sugar spikes. Drink water to help hydrate you and also it can help when insatiable hungry. I did this the other evening after having a carby lunch when eating out and being away all day, which kicked off junk food cravings and the water help settle my tummy so i could go to sleep and not cave in, then the next morning i still wasnt as hungry as expected, the carbs must have set off the cravings.
Get enough sleep and try to keep relaxed as cortisol stress hormone leads to hunger and carb cravings.
If you exercise it will help build more muscle which burns more calories.
I'm tapering down, currently from 15 to 12.5 and feeling more hungry already but its good so far and manageable, but I'm also tracking on myfitnesspal so I can see what I eat and keep control of it.
I'm also going to take liquid berberine which is an appetite suppressant and lowers blood sugar, but that's because I was prediabetic and from a young age had insulin resistance.
I've heard the hunger settles after a few weeks, so just try to get through the initial phase and then it will normalise.
I've got a 15mg pen currently going down to 12.5, then 12 then will do 10.5. Then I've got 2 x 10 pens as the higher were out of stock so I'll taper down with them further. They say the best is to come down slowly, at least a month on each dose but with the price rises a lot will be in the same boat coming down a lot quicker or going cold turkey, especially if like me they reached the top.
