I would get that feeling when I was at 36 so I went back down to 27 and have been fine, the feeling I got was as if I hadn’t eaten in a long time and had the shakes and irritable. I knew it was the dose partially because if I would eat a big meal, afterwards the shaky hungry feeling would still be present, hope that helps a bit
