Heres one for you , I have checked good ole google and cant find anything , so have eneded up here , ............ This problem started quickly at lunch time last thursday , each time I swallow food , about 4-6 seconds afterwards I feel very light headed and sometimes it seems like I am going to pass out , If I drink water its not so bad , if I drink something fizzy its medium , if I eat a fork full of solid food its very bad . It will also come on to a lesser degree when I am just sitting , When it happens the feeling will last for about 5- 10 seconds , ifs its very strong a bit longer . If I stop eating it will not occur .
