I had these pretty severely in my early stages of recovery. Some attribute it to major hormonal fluctuations and some say it is a heavy boost in metabolism. I figure it is a bit of both. It was especially severe for me when I had a large meal… I would wake up soaked in sweat. I am not sure if this hinders weight gain, but I will say that it takes more food than you probably think to make repair and restore. Good luck!
