Obtaining Meto (or similar) for SN CTB

[helpless_soul96]

Been having a really tough time getting Meto (or similar). I have a history with my Gastro, and she recommended Zofran. She seems reluctant to prescribe a dopamine based drug. Should I just take the prescription and say it doesn't work? Then hope she prescribes Meto? I am suffering a lot and really just need to CTB, but with pain hyperacusis (noxacusis) I'd get permanently worsen pain if I were to vomit and fail.
