I used to have this problem.
My solution: I drink a sugar-free Redbull when I wake up in the morning and something caffeinated during lunch (like a diet Coke). The only downside is that when I don't drink a Redbull in the morning, I am groggy the rest of the day. You could also try drinking coffee in the morning and something caffeinated during lunch.
