yeah - I notice when my blood sugar drops my heartbeat goes up, pounding would be a good word. I eat 2 scrambled eggwhites for breakfast every morning but if you're vegan you could eat legumes and get the protein you need. Actually I increased my protein recently by adding kidney beans to my breakfast routine, only 1/3 cup but the extra protein/carbs combo seems to be a big help. Also, did you eat when you got home??......protein and carbs?? we each have vastly different things we eat for breakfast when we ride -

this might help you! I also keep Larabars or Luna bars around, they have a very nice protein/carb combo that will hold me over until I can eat or as an energy bar during a ride. Hope the link helps, and let us know what happens!
