Aaron, unless your friend is "hiding" her condition from her co-workers, I suggest that she take a half tablet and put it under her tongue at the 2 hours and 50 minute mark. Mestinon used sublingually takes about 10 minutes to start acting (at least for me). OF COURSE she should run this by her doc, FIRST! (Or do it at the 3 hour mark if she'd rather NOT ask her doc -- her symptom recovery will be 10 minutes as opposed to 30 minutes.)

Mestinon melts fairly quickly under the tongue and does not have an unpleasant taste.
