I've been on Cymbalta several months, and I've noticed what I couldn't name but what others have described as vertigo or a spinning sensation. This can happen when I'm sitting down, standing up, moving, etc. and it's tingling that radiates through my body combined with a weird dizziness. It worsens when I'm tired. Has anyone experienced this before? Other than changing dosage, which my doctor has suggested, has anyone had success in dealing with this? Thanks for your help!
