I have had worsening dizziness since my PD diagnosis last December. Lately I've been very nauseous, too. All the time. Being treated for orthostatic hypotension, (midodrine 5 mg 2 x day), but when I check my pressure standing, it's normal now. When I first started the carbidopa levidopa it was like a miracle had occurred. Now, even though I'm taking more doses (3 tablets 25-100 mg) six times a day, I can barely walk. I have to take Linzess, Paxil, Remeron, and Xanax, all of which cause dizziness. I take Comtan 200mg with each Carbo/Levo dose as well. Zofran does nothing. I also suffer with spastic bladder, and as soon as I'm drifting off to sleep, I start to go! And by then I can't get out of bed in time, last night I couldn't move at all. My poor husband! My yoga classes are impossible and I won't be able to drive soon at this rate. I have thrown up everything I've eaten today, Somebody please help! I can't live like this!
