I also have acid reflux, caused by a haitus hernia.
It may have been the pepper that started you off - my reflux is agitated by bacon and sausages, so I have to forgo the sausages, I will risk the bacon because it doesn't always kick off.
Try not to eat anything after at least two hours before you go to bed, and make sure you have at least two pillows -I think those wedge pillows look uncomfortable - two good firm pillows will do the job.
The digestive system is very good at healing the acid burns quickly and effectively, so don't worry too much about lasting damage.
I always have a glass of milk, which I sip slowly sitting upright - downstairs watching TV usually, and then pop a Gaviscon in when I head back to bed, but try and make sure it's all gone before you doze off. If you are a quick sleeper, try the liquid Gaviscon.
