Take the gas pressure off.
If you want to serve it tomorrow,keep it cold,and go by the keg and burp it every hour.
After course of today, with this regimen, check your pour, with the gas still disconnected.
No?, keep burping.
Get up in the morning and try one for breakfast, after burping.
How is it now?
Can you live with it?
Determine whether you are going to start serving with "residual carbonation", and then make the call whether or when to hook it back up @ serving pressure.
