I Haven't Had A Lot Of Symptoms Of Ms Since

I haven't had a lot of symptoms of ms since 2008. I'm traveling to Cancun for 9 days. I'm concerned because being a woman with a "shy bladder" or whatever...holding all that water, drinks, foods, etc. plus the complication of an illness...I'm not sure what to eat and drink to be completely safe.

All the fruits and veggies are available...it's more of what to eat and drink to keep my system working.
