Which foods and drinks should you avoid before going to bed, if you hope to get a good night's sleep?

this is easy. In my experience, avoid taking anything that are high in caffeine before you sleep. I'm quite sensitive to caffeine, so I avoid drinking coffee, Coke and strong tea about 3PM onwards. Sweets and spicy foods are also, in my opinion, bad for good sleep since you'll be stimulated by the burning sensation in your guts or the rush of something sweet. But again, this will depend on the person and how tolerant they are to certain foods. But, from my experience, the best natural sleeping pill for me is a tall glass of milk. Exercising during the day will also help you reach dreamland faster, just make sure to cooldown properly.

That 3rd bottle of Red wine, and a bag of Doritos.

Don't do it.

Pickles with ice cream. Talk about Blade Runner dreams then Chariots of Fire to the toilet when you get up.

Anything containing E-coli.

Good daytime exercise seems to be very important. Eat regularly, and try to avoid any mental stress. Some people say caffeine keeps you awake but somehow it does not bother me much. As someone mentioned, that must depend upon people.

That 3rd bottle of Red wine, and a bag of Doritos.

Oh yes, but easier said than done when the football starts at midnight.

Probably coffee...

Pizza! But I agree with @kohakuebisu, it's tough when football starts at midnight, and as @spinningplates said, that 3rd bottle of a fine red wine (if I make it that far) and those delightful Doritos (the hot ones) are guaranteed to bring on nightmares. But, I LIKE nightmares.

Anything with caffeine is probably a no-go. Sugary things also should be avoided. For me, having some hot chamomile tea before bed is quite soothing and helps lull me to sleep.

Sardine and peanut butter sandwiches with a milk and Pepsi chaser.

I eat when I get hungry and my body could care less what time of the hour of the day or night, and I never have a problem with sleep, ever.

The same foods you should avoid any time of day - processed foods, high sugar foods, foods high in simple carbohydrates etc.

A glass of water with a 1/2 teaspoon of baking soda before bed,

sets things to right...
