well know how the 'intake' and outgo affects how well one functions? Well, IF Alan hadn't eaten, nor hydrated properly for quite a while before his 'event'...it's not rocket science...
As for blood tests? One cannot slurp too much water prior? Unless advised otherwise...You gotta get juice into your veins to get them easily 'tapped'. No ands, ifs, or buts. More juice in 'em, easier the process. Same goes for infusions? Give them 'juicy' veins and the rest is easy..if not problems can occur.
I used to be and maybe still am hypoglycemic...kind of the opposite to Diabetic, but actions, reactions are similar? The key is the getting foods into you that are processed correctly and at the right rates...Too much or little at the wrong times...well KABOOM! Flat out cold or near so...Not pretty at all. Now, Alan's a grown person...tell him to either let you know or let you know when he's gonna be in situations where this mite happen. For me, such situations are kinda predictable...as in no food for key periods of critical times? For my Hypo condition, well, I just tote some crackers and cheese slices [about 3-4] to get me over any 'humps'. For a Hypoglycemic, the processing and sugar/carb curve goes slower with the carbs. For a Diabetic, such a solution would NOT be the best approach...I'm not well trained in that quarter.... I just wish I could be more useful?
Doesn't mean that I don't HATE those passing out sessions tho! Those aren't fun for any reason, wherever and however they happen! Here is to them NOT happening again? - j
