Take a dose of Maalox or Mylanta, and at the same time, take a 150mg ranitidine tablet (Zantac or generic)
This should give you 12 hours or so releif
If it is a problem that keeps comming back, buy some Omeprazole (Prilosec OTC or generic), and take one every morning.
All of this is assuming that you are sure there isnt any serious cause for your symptoms..... have you mentioned them to your doctor?
