These are another set of culprits for people who are having trouble sleeping. If you are prone to not sleeping, it is best to avoid foods as well as drinks that have high caffeine content such as coffee, chocolates, and sodas that are caffeinated as well as teas. To get better sleep, it is best to not consume these for a while. Or if you really cannot do without these, try minimizing your consumption even for a couple of days. Once you get your sleeping pattern back, you may go back to consuming these but only to limited content so you would not go back to having sleeping problems again.
