Hi. I haven't seen a specialist yet so I haven't been diagnosed with SD but I'm certain I have it in some form (if perhaps less serious than others) but I have a massive throat clearing thing.It happens after eating especially. It only happens after drinking if I haven't had a drink for several hours (say when I was at work) and then it would be like a shock to my throat to be given a drink and it would need to be cleared for some reason.
Also every morning when I wake up I have to cough and clear my throat for about 2 hours constantly before I feel like I've dislodged what has maybe collected from during the night before.
Just my own little self-diagnosis! :P
