Speaking of food, people are advised not to eat too much before bed. I don't have that problem aside from usual overfeeding and associated discomfort, so YMMV.

Similarly, many people claim that you're not supposed to drink alcohol before going to bed if you want to sleep well, but IME (based on both subjective feelings, what smartphone accelerometer-based sleep trackers tell me, and my performance on stuff like Quantified Mind or Lumosity the following day) the reverse applies to me.
