For her, the grapefruit tasted like one of the ""sweetest"" ones she'd ever had.<br /><br />However, the real treat for both of us came with the lemons and limes.  Both of which tasted noticeably better.  However, the effect of a single tablet wore off completely within 5 minutes.  To be honest, I hoped each tablet would last closer to an hour, but as is, you're paying quite a bit per minute for these things (we paid ~$20 for ten tablets w/ shipping).
