Moving to Ambergris Caye Belize

Hi,
Will be moving soon to Belize, but unsure of one important thing. I have sleep apnea and use a CPAP machine at night to sleep. The machine needs steam distilled water. Do the supermarkets or pharmacies sell steam distilled water as they do here in Canada and at what price?

I am certain they do, but I have never had the need to purchase that, so I can't really help you. Almost everything available in the US and Canada is available in Belize- may not be your brand, and it might cost you a lot more, but I am sure you can get it.
