Thank you all for sharing your experience and providing valuable feedback, greatly appreciated!
Since this my first time, I am planning to acclimatize for couple of days and plan to go slowly (plan to take 8-10 hours for ascent). I am hoping that this is good enough to avoid AMS symptoms. I still want to carry Diamox and but don’t plan to use it this time unless I really need it. It looks like from couple of feedback, I can still take 125mg Diamox if I experience AMS symptoms while hiking Whitney if I am drinking plenty of water?

Thanks
