Caffeine[edit]

"It has also been shown that 1–2 cups of coffee or 1–2 mg of caffeine before bed can prevent hypnic headaches". You may want to check this, one cup of coffee contains about 60mg of caffeine. Even de-caff coffee has about 8 mg caffeine per cup. — Preceding unsigned comment added by 86.160.148.236 (talk) 12:04, 17 December 2011 (UTC)[reply]
