Key point, right there. If you've got questions about something your doctor said or did, ASK! Speak up! If you want an explaination, they should be prepared to expound on what they recommended right down into the chemistry of the thing.

The numbers of the dosage are a really bogus way to quantify an effect. You don't know how potent the stuff is unless you've studied pharmacology. A whole mg of that stuff might knock you right off your feet for all we know. 5mg might kill you, for all we know. We don't know, that's why we hire doctors. Other meds don't even START working until you get up past 500mg. You can't compare them.
