JessicasWLSJourney 15 Posted March 13, 2018 Yesterday (Monday) was day one of my pre-op diet. I'm allowed 2 Protein Shakes, a smart meal, and a smart snack per day. I had all but the snack as I didn't need it. However it's almost 5am and I still haven't been able to fall asleep. Is it normal to experience insomnia and restlessness during the pre-op diet?

James Marusek 5,244 Posted March 13, 2018 No, not always. Understand that you are about to undergo a major operation and the fear can cause additional stress and restlessness. Also you were probably given a requirement to offload caffeine. When I gave up my caffeine habit (6 diet cokes a day), I suffered through a week of caffeine withdrawal syndrome which consisted of severe body aches and headaches. This might also be a potential cause. Share this post Link to post Share on other sites
