I agree with gr8guymemphis, I slowly came off Lexapro and had similar feelings/symptoms etc. I also went onto 5-HTP( I call this the NATURAL wonder that doctors don't want you to know about) with a combination of St Johns Wort and Vit B and the awesome thing is the only side affect that may or may not occur is feeling a little nausiated in the first few days as your body adjusts.
Although I'm no physician, I do know from experience your symptom -- it's a combination dizzy / light-headed / "buzzy" feeling (mine even accompanied by a sort of popping sound on occasion). Frantic, I tried lots of alternatives, but what worked best for me: OTC meclazine (Dramamine, or other) for the acute symptoms, and 5-HTP / St. John's Wort / B-Complex supplements for longer-term management. I PROMISE YOU, although it will take time, YOU WILL GET BETTER.
By 'inner ear problems' I presume you are talking about vertigo? That is not a typical SSRI discontinuation symptom, but some people do have unique symptoms. At the same time, it is possible that the symptoms are unrelated, and that you coincidentally developed a viral infection of your inner ear. I would expect you to argue that point-- as people tend to associate things together when they occur at the same time.
Discontinuation symptoms can be avoided by tapering an SSRI slowly. Another way to avoid withdrawal is to take fluoxetine (Prozac) for a few weeks after stopping Lexapro (or any other SSRI), then simply stopping the fluoxetine. The very long half-life of fluoxetine causes it to leave the body over a period of months, tapering so slowly that the person doesn't have any withdrawal.
My recommendation at this point would be to go back on a low dose of Lexapro--maybe half of what you used to take. If the symptoms go away, then you know they were related to the Lexapro; you could then taper more slowly, or do the fluoxetine thing. If you still have vertigo after a couple days on the small dose of Lexapro, then the symptoms are not part of Lexapro discontinuation. The latter outcome would not surprise me, frankly...
Another option would be to take meclizine for vertigo and wait it out. But I think if it were me, I'd want to find out if the symptoms were or were not related to the Lexapro.
