Same! I’m on Elvanse for about half a year now and the first week was insane, I had to force myself to eat, which never happened to me before. I also lost a bit of weight in the first 2 months (which is not a good thing for me), but I got used to it. Now I eat a huge breakfast, before it kicks in and then just eat small amounts over the whole day and have a bigger meal once it wears off. But I definitely had to change my routine a bit. I miss enjoying a lunch break. :D
