Hi Debby. I too have had this feeling of drunkenness when I sit or stand. It started about 16 months ago and has progressively worsened. It goes away when I lie down. It is not vertigo. I finally saw my ENT and it looks like my symptoms are from a condition related to aging (I am 76) called Presbystasis. It is common and incurable but treatable. Treatment consists of balance training mostly so I am waiting for a physical therapy referral. I highly recommend you see an ear-nose-throat (ENT) doctor. After 16 months of seeing a plethora of specialists, I finally have an answer. I keep a positive attitude and look on the bright side. The blessing has been that in my search for an answer, a small aneurysm was discovered in my brain that I have had treated with a type of "stent" that will cut off the aneurysm blood supply and make it go away! Praise God! Keep us posted if you like on your journey. I hope this helps.
