Tinker, are you on any medications that might be having an effect on you? Have you had any episodes of other GI discomfort that might play into this, or any symptoms other than those you're describing? When you're vomiting, are you bringing up food, or just liquid? And if liquid, it is clear or is there a color to it?
Hi there!
These are likely to be mild episodes of food intolerance or GI inflammation/ infection. You could try taking plenty of fluids and some OTC anti-emetics for symptomatic relief. If the symptoms become longer or become increasingly recurrent you may consider an evaluation by a primary care physician
Hope this helps.
Take care!
