I like Dimetapp for colds and allergies. I also took it when I had to take a long, unexpected plane ride. I really, really dislike flying, but the dimetapp calmed me... w/o knocking me out like Benadryl or Nyquil.

Chamomille herbal tea is great for heart burn, as I used to have acid reflux. Mint gum is a quick fix for heart burn as well.
