Welcome to HealingWell!
It sounds like you're having bloating issues. Have you tried taking any OTC meds like Gas-X or Beano? They seem to work pretty well for me at keeping the bloat down. You can also try peppermint... Peppermint tea works pretty good. So does fennel tea.
Another thing to try is to get moving. Exercise helps keep the gases moving which help keep the bloating to a minimum.
Do you drink soda? Carbonation in soda sure makes us puff up.
Hopefully others will be along shorly to give their input.
