I realise I sound ridiculous but I cannot yawn properly - as in my yawns begin but then feel somehow too conscious or intentional - not natural. And also, they don’t complete - it’s a bit like if you think you’re about to sneeze and don’t.
I’ve had all my loading doses and most of my symptoms have dramatically improved, but I’m convinced this is associated but whilst i think it has improved some it is still happening. Anyone have any ideas what exactly causes this?
Hi Roo32 . Yes, I've had that before plenty of times where I felt like I needed to yawn only to find it wouldn't complete or couldn't get enough breath in or just not refreshing. You don't sound ridiculous at all 
All the best

Thanks Greg, did this resolve after some time?
Mostly resolved yes. If i overdo my yoga practice or get stressed it can return, which is telling me I'm still going through the healing process, but way better than before. I'm 9 months in since my first injection BTW.
I didn't yawn at all . I only realised when I started to yawn again . A nice familiar feeling. I was very ill at the time a year ago. Yes I agree odd. But real.
EXACT same for me. Was a very persistent symptom that finally resolved with only occasional revisits, also when overtaxed or stressed. It was weird and annoying.
Yes!! Before I started treatment I stopped yawning completely. My sense of smell was gone, to the point of having an onion right under my nose and ......NOTHING! I used to cut an onion in half and the water works would start. I stopped sweating. I had to concentrate on breathing as I would find myself sitting there and not taking a breath for quite a while. About a month into injections all but the smell returned. That took a couple months longer. There are some strange symptoms let me tell you.
The yawning reflex is quite complicated and can be affected by many things. Antidepressants are known to have some effects.
When I was working in the pharmaceutical industry I used to volunteer to test our drugs. One of the antidepressants, caused a strange, distinctive, yawn. So I looked in the scientific literature. I found one paper that spread around the whole industry - it went photocopy viral (this was back in the early 1980s). baillement.com/clomipramine...
Haha!! Well that is fascinating, and in many respects puts my own situation into perspective. Who knew yawns were such mysterious things!
I never have proper yawns now- just a series of automatic overlapping yawns that are noisy like sighs - I used to get embarrassed when people turned round to stare, but I'm used to it now. If I smile, they laugh - mostly I think I just made them jump. It goes on a bit long sometimes but is a lot better than it was.
It is called "air-hunger" and quite familiar as a B12 deficiency symptom to those who have/ have had it. Not so much with GPs, where it seems more likely to be thought of as a nervous thing . It isn't, as it happens most often when very tired or depleted, and can happen whether in the tube/ supermarket queue/car or just on waking. Trying to push more air into lungs- so the exhaling part is what is missing.
Have now not yawned for 4 years.
So is it like short gasps in succession.? I get that if it is.
For me, yes. Does it get worse if you do more ?
When I was really bad, I would be doing this over and over in the supermarket and in the car on the way home, until finally throwing all the food into my fridge, freezer and cupboards, throwing my glasses onto the coffee table, throwing myself onto the sofa and sleeping immediately for about 3 hours.
At least that doesn't happen any more !
Long time no see, a brief update from me and a daughter with a diagnosis…

Why am I not getting better?
