Peppermint and ginger are both things that help settle an upset stomach. I would suggest looking into a quality loose tisane (or even making your own) with one or both of these two things because the teabags you buy in the store are either going to be flavored, old or just bad quality.

Tramadol comes as a tablet and an extended-release (long-acting) tablet to take by mouth. The regular tablet is usually taken with or without food every 4-6 hours as needed. The extended-release tablet should be taken once a day. Take the extended-release tablet at about the same time of day every day, and either always take it with food or always take it without food. Take tramadol exactly as directed. Do not take more medication as a single dose or take more doses per day than prescribed by your doctor.
