I don&#x27;t drink coffee at all. I eat a vegetarian sandwich every morning when I go to work, it gives me a good start for the day, I feel sharp and focused all morning. Sometimes when the sandwich shop is closed I buy something like a chicken sandwich, and that makes me more sleepy and tired.<p>Lunch is usually a big pile of rice with some vegetables and meat. Wow, this makes it reeeally hard to stay awake at the afternoon, but there aren&#x27;t many options for lunch near the workplace.<p>For dinner, my wife cooks something also usually rice with some meat and veggies. But about 1 hour before I plan to go to sleep I eat 1 or 2 bananas. I always had hard time sleeping, and I read that bananas are good for sleeping because it contains potassium. For me it works. Although this might be completely placebo, because bananas don&#x27;t work for my wife.
