This is the major problem I face at work. While looking at the computer screen, I start feeling dizzy. When I walk, I feel like fainting and weak. I cannot reduce my dose, I'm already taking the strict minimum. Any alternative techniques out there to fix this?

I get dizzy whenever I stand up too fast.  I have to get up slower, and I used to not need to before.  I have a blood test today specifically for the spiro so we'll see what's up!

Talk to your doctor, it could be a lot of things.
