Buying diet ginger ale before cruise

We are cruising out of San Juan in November. As a diabetic who has a tendency to get sea sick, I try to bring diet ginger ale on board with me, since it is not available on the ship.

Is this something I will be able to find in San Juan? We will be flying in the day before and I'm not sure where we are staying yet. I see that SuperMax seems to be one of the main grocery stores. Does anyone else have any suggestions on where I can look for this (I'm not particular about the brand)?

Thanks!

Apart from the Supermax supermarket, there is a Walgreens and a CVS right across the Old San Juan cruise docks. If departing from a ship that sails from the PanAm pier (RCCL, Celebrity, Norwegian) you will have to make arrangements to stop by a supermarket on your way to the pier since there are no stores near it.

Thanks. We're sailing Norwegian, so I'll make a stop at some point. Do you think the Walgreens or CVS will have diet ginger ale? I know it's not the most common thing.

Yes CVS\ Walgreens has diet gingerale

Thanks so much for the confirmation!

Have you inquired if the ship will have it or get it for you ??

They have other sugar free sodas so why would they not have ginger ale
