I notice that it's effect wears off. The first time I took only one, it was noticeable then that effect diminished, then 2, then 3. Now the thing is the size of the bm is the same if I don't take it and use a carrot or sometimes with no carrot it's the same size so I thought this was interesting. In other words when I take CS, I have to take more to achieve the same effect as when I took it in the beginning or it's the same as not taking any.
