Tizanidine

I was just prescribed Tizanidine as a preventative for VM by my neurologist. Pretty sure she doesn’t know much about VM and after reading the main side effects of this muscle relaxer (dizziness, unsteadiness, lethargy) I’m kind of nervous to take it. Just wondering if any of you take it with success as a preventative. I know everyone is different just looking for opinions of fellow VM’ers!
