Tablet Puzzle.

An interesting puzzle I came across :

Puzzle :-

A patient is given 2 vials of tablets labeled A & B. He has to take one tablet from each vial dialy. Neither can he skip nor can he take overdose, as either of this would prove fatal.

One day - after taking one tablet from vial A, 2 fall from vial B. Now he has 1 tablet from A and 2 tablets from B. By a clever logic - he manages to avoid overdoes even though there is no way to differentiate the tablets to be from A or B. They are same in color, texture, size, appearances. Of course, he does not waste the 3 tablets, i.e. the solution is not to throw these three and take 1 from A, and 1 from B :)

Solution :-

He divides the tablets into halves. He gets 2 pieces of each. After this he consumes of one half of each. i.e. he would have consumed 2 halfs of tablets from B, making it a single B tablet and 1 half of tablet from A. now he takes another tablet from A, divides into half, and consumes it. He preserves the remaining four halfs for the following day.

Clever, ain't it ? :)
