It seems to have worn off already. He's not keen on eating and his (small) meals are now off the back of the spoon, usually in about 3 different locations in the flat. He's on Pepcid every other day, but so far that's made no diffs either. I just hope I can get enough down him to keep his weight steady. His cold is horrible today but that doesn't usually make such a diff to his appetite. SEB doesn't seem to have helped much either. This morning was the very first time he turned down most of his i/d breakfast - I subsequently got some of it down him via the spoon - but up until today that's the only meal that he was hungry enough and enjoyed enough to eat off a plate (albeit perched on top of the radiator).
I read somewhere that some people give a steroid as a weekly jab, but that doesn't sound too good for him (??). Plus I think he ate well as a result of the B12 jab. I don't think you can give those too often either.
