<s>[INST] A few years back I woke with the whole room spinning which caused me to instantly have to vomit. The sedation did not stop and the only thing that could stop the sensation was to curl up in a little ball on the floor with head facing the floor. If I even moved my head a little each way it would cause the violent vomiting. My wife took me to hospital where I sated all day until it subsided. The doctors tried numerous drugs to stop the symptoms but not a lot worked. At the end they did not know what caused it. Since then I literally went to bed each night for a couple of years terrified it could happen again. I can honestly say it was the worst experience of my life. Well this morning the same thing occurred but I managed to wake AS SSON AS IT HAPPENED and was able to stop it setting in. As I was terrified I just sat up still with our moving my head as I always thought that lying on my side or moving my head to the side induced the symptoms. After about five minutes I leaned over to pick up my glasses and the sensation began again. I am now very afraid that ut is going to start again just like a few years back. I have been drinking water and I feel very burpy and I feel that it is only a matter of time until I have to vomit. It is not the vomiting that I am afraid of it is the spinning sensation which I can not describe how intense and traumatic it can be. I am 47 and pretty robust however I can remember crying to the doctors to make it go away. Please help or suggest somerthing so that I do not lapse into the same thing as last time. [/INST] Hello, Regarding your concern, I would explain that your symptoms could be related to an inner ear disorder.  For this reason, I would recommend consulting with an ENT specialist for a physical exam and labyrinthine tests.  It is also necessary for checking thyroid hormone levels in order to exclude thyroid gland dysfunction.  Hope I have answered your query. Let me know if I can assist you further.   </s>
