Diclegis not covered... I cried 😭

My insurance will cover 0% of diclegis so it would be $750.00!! My doctor gave me a coupon for it to be $30. Or so I thought. Apparently I didn't read the fine print. It can be "as low as $30". The coupon made it $250. Still way too much. My doctor offered zofran. I cried. I don't want to take zofran because of the potential risks. I'm sending my husband to get unisom and b6. Hopefully it works the same
