I have the same feeling but since I have had IBD for 46 of my 55 years I haven’t attributed it to the IBD, but rather the poorer quality of sleep I have experienced as I have gotten older. Much of that is due to my sedentary work and lifestyle. I have observed that my highest quality sleep comes when I am most active both physically and mentally. Unfortunately the physical part lags behind the mental due to sitting at a desk and working at a computer most day. I sometimes wake up and feel as you do, not sickly but lethargic, and I need to drink an extra cup of coffee in order to have the requisite energy to go about my work day.
