Great advice from Marianna. I'll add just two things that I just thought of:
1. Valium is derived from valerian root. If you don't like taking drugs, you can substitute valerian root extract (available in liquid or solid-extract form at many health food stores). Valium will be stronger and therefore possbily more effective, however.
2. It's a good idea to keep walking daily, even though your symptoms may be uncomfortable. Walking exercises your brain's sense of balance, which it derives from three sources: your vestibular nerves' signals, what your eyes see, and the propioceptors in your feet. And exercising that sense speeds how quickly your brain adapts to (learns to ignore) the aberrant signals your compromised vestibular nerve is sending to your brain. So walk, walk, walk!! Your symptoms will improve much quicker.
Best wishes,
