Ileostomy and Diamox?

I have had an ileostomy for many years.  I'm traveling to high altitudes in the fall for an active vacation with lots of hiking and walking.  I often deal with dehydration (from both somewhat high ileo output and heavy sweating during exercise...) and I'm able to correct fluid loss/ electrolyte imbalance with the use of oral rehydration fluid (Ceralyte products) and lots of fluid intake.  I'm wondering whether the use of Diamox for altitude acclimitization would be a bad idea or not?  I've understood that it is not a strong diuretic, but should I stay clear of diuretics all together?  I want to enjoy the trip but not put myself at risk for an intestinal blockage of kidney stone.

Thank you,
