Thanks guys for your advice. I have reflux which doesn’t give me heartburn but flows into my oesophagus and has caused a lot of acid damage to my ‘voice-box’ these past few years it sucks coz my voice only really lasts about 3-4 hours of talking a day.(I have tried all medication and totally changed diet).
Anyway, that was good to hear an experience of someone fit so it sounds pretty good. I should hopefully be getting it in a few months and most forums are not full of err larger people.
