this may seem like a very unusual question....i am only on day 5, however something happens after i do the warmups, or during, but not while singing songs though...i burp.  will i overcome this, is it normal, what am i doing wrong, lolol

I'd experiment with avoiding food or carbonated beverages directly before singing, and if you have acid reflux, that could also be a factor!

I haven't encountered this personally, but forums on Reddit or another similar site may help crowdsource info on burping while singing.
