Smoking cigarettes instead of drinking coffee to stay awake is like jumping off of a skyscraper to avoid a fistfight.swolf said:Soda? Or smoke a cigarette (they have some caffeine I believe). Neither one is good for you but I think they have less caffeine than coffee. You could even try drinking Caffeine-free drinks, like Sprite.
Anyway, you have got to get over your addiction first. Caffeine addiction is a real thing, but the symptoms go away after only a couple of days without the stuff. It's going to suck, but you'll be MUCH happier without it. After you've finished clensing yourself, try exercising in the morning. I used to be very tired at school, but after I started biking there (about 2 miles) I could stay awake much better. You might also want to try drinking juice, especially apple, in the morning instead of coffee; as that is a pretty good way to stay up.
