I see the time of your posting - so you have probably resolved the situation by now.
If your stomach wants to reject its contents, it is often kind enough to give you fair warning - and this is what you are getting.
Unfortunately, as advised, there is no way around it, and you are only delaying the inevitable, but on the bright side, the feeling of instant relief when it's over.
Lean over the bowl, shut your eyes, oepn wide, cough, and let nature take its course, always better afterwards.
