Very recently (2 days ago) while I was out for a walk I experienced a very dry mouth. No saliva. Felt like I was going to choke (usually have a water bottle with me, not this time). This was the first time and I tried not to panic... so I stood still and didn't breathe. I found a little bit of saliva & swallowed and try to find somewhere I could get water or gum, etc. Has anyone else experienced this? You could imagine it was very frightening.
