Hey Digby,
Figured I'd chime in as well.
Antivert is usually prescribed for those with some type of motion sickness (ie: flying, cruise ships, driving, etc). I tried it for a while and for me, it didn't do bupkus. I had heard from some on the Cyberknife Support board about low dose (short term) valium. My radio-onc prescribed 2mg Valium 2x/day for a couple of weeks and for me, it did help. Didn't affect me at work or to function... and did help my balance issues (I have balance issues due to the AN as well as Chiari 1 and walk with a cane). For me, the low dose did help... and as we know... "individual results may vary". I don't like taking meds at all, but was willing to give it a try... and for me, it did help.
Hope this helps.
Phyl
