I couldn't sleep, just laid in bed for a few hours and read.

I drank over 70oz of water before, during and after that ride.

Today, same thing 35 miles at 15mph pace, I ate an ommelete and some yogurt. I'm again in bed - really tired. 80oz of water today.

Prior to both rides I eat a bowl of oatmeal and a banana. I'll have a bar on the road.

What can I do to prevent the onset of exhaustion after riding? I was thinking maybe some type of sports drink.

I'd like to ride in the morning and have a normal day.
