I'll keep it short and sweet! I'm sure there are hundreds of methods out there, but these are the core ones that I've found to really work:
Hydrate with water
Relax and unwind - you may opt. for a hot bath/shower or a hot water bottle to relax your digestive system
Low impact/intensity movement like walking, yoga or stretching
Tea containing fennel, mint, or ginger (the best in my experience)
Digestive enzyme supplements or peppermint oil/capsules
Food sources: cucumber, ginger, and yogurt (natural, no added sugar or artificial sweeteners)
Integrate spices like turmeric or cayenne pepper into your following meals - fennel seeds are also great to cook with.
Apple cider vinegar - consume two tablespoons diluted in water (optionally add some lemon juice) and sip over the course of 10 minutes or so
Ride the wave - sometime's accepting the situation and being patient is the final remaining remedy
