I have not had caffeine since before my surgery on 9/27, but strangely my mind is like on overdrive or something and I can't seem to fall asleep easily at night. Getting up in the morning is a challenge but probably because I have been falling asleep around 1-2 am on average instead of 10-11 pm. Anyone else have this issue? I would think the no caffeine (diet coke was my love before surgery, not missing it now) would be making me more tired if anything.

I had that problem early on as well and after some online research, I decided it was due to the high Protein, low carb diet. Apparently, that can cause temporary sleep problems.

As my body became accustomed to my new way of eating, the problem waned. I no longer have problems getting to sleep but it lasted for about a month. That's my explanation for my problem based on the fact that nothing else had changed in my life at the time. Hope it helps you.

When you are on very low calorie diet, your body remains hyper-alert for any potential sources of food.

I guess that makes sense. Hopefully it will pass soon.
