Night time acid reflux

Has anyone else had this? The last couple nights I woke up to acid in my esophagus & last night it caused me to start choking. I was coughing & puking for a good 10 mins before I could finally calm down & my throat still burns. Anyone else ever deal with this before? I go to the doctor Tuesday & will ask about it then, but does anyone have any tips that might help? So far sleeping almost upright is the only for sure way I've been able to get any sort of sleep.
