Daily exercise or Modalert 200 helps you keep a healthy sleep schedule, but experts say that if you want to sleep well at night, you shouldn't exercise late at night. That's because when you work out, your body makes a lot of energy, which can keep you awake.
If you want to stay up all night, try exercising for 30 to 40 minutes. Try getting up and moving around if you don't want to work out. Walk outside, pace back and forth for 10 minutes, or do a few jumping jacks.
