I am 4 weeks post-op tomorrow and had issues with hypoglycemia pre-op. To be honest my hunger is so different now. Now, I notice that if it has been 2-3 hours since I've eaten I feel that little drop in energy or I start yawning, grinding my jaw etc. I know it is time to eat! When I was first out of surgery for the first week I was afraid to eat or drink because it was uncomfortable. I definitely think my blood sugar was low because my energy was gone. I notice that the days that I start with a Protein shake that prepares me to have a good day. Really as long as you listen to your body and eat every few hours I haven't had any crashes.
I went to a family dinner and bowling night last weekend. I brought a little cooler with turkey meat and cheese in the car and ate twice throughout the night. I have just learned to be prepared and I won't get into trouble.
Best of luck, this is really a journey, but I am thankful I took that first step!
