Your symptoms also mimic food poisoning. If you can recall [no pun] the name of the PBC's see if it's listed here. http://www.accessdata.fda.gov/scripts/peanutbutterrecall/index.cfm
My guess is you were experiencing a combination of effects from your illness, antibiotics and the sugar overload. However, I think you really need to examine your diabetes management. Do you test? If not, you should, and you would get a frightening glimpse of just how high all the **** you ate drove you. You make it sound as though you had no choice but eat and drink all that sugar! You had water available to you for thirst so why drink three regular sodas? As for the large peanut butter cookies, not much can be said. As a diabetic I strongly suggest if you are going to be out for a period of time with no access to healthy snacks, you carry your own. Your health, not your golf game, should be your priority. It will be hard to play golf if you have your legs amputated due to diabetic complications.
