Vomiting with NO food returning?

[Guest guest]

Hello,

Since the topic of vomiting/barfing/p.b'ing came up I thought I

would ask my question.. I have on more than one occasion found myself

over the sink AFTER a meal.I have a thick mucous come up but NEVER

food.How can I just swallow food get up and go to the sink and NOT have

food come up when standing over the sink?How can I be heaving and not

heave the food up that I just consumed?Where does the food go? Just

curious as I can't seem to vomit(traditional meaning here) at all post

op 6 plus years now. Any idea what is going on? Is this normal?

Thanks
