That said...and I'm still not an expert...if "Ativan" is the same drug (I can't find an "atavan") then it sounds bad...the "relief" you are feeling could well be just the sating of an addiction...sorry. 🙁. If it helps, think I may be experiencing something similar with Baclofen. Doctors. They put us on these things and don't stress how much of a problem they can cause compared to the one they solve.

Low sodium is hyponatremia, does that sound right?
Best person to ask is a doctor, or maybe a few doctors. Parkinsons or "movement disorder" specialists if possible. Forums are great for comfort, experiences, suggestions, and strategies, but we are for the most part sufferers and carers, not experts, and some of us will take risks with our medication when we are desperate for relief.
