It would depend upon a number of variables. If I knew the person giving me the potion, then maybe. However, I find it hard to believe that I would actually drink anything given to me by someone only categorized as 'mysterious' <..< Unless he was Severus Snape.
Keeping with the theme of sense though, I would say that if any sense were to sharpen, I would hope that it'd be my eyesight or hearing. As it is, I have to wear glasses, and I'd love it if my vision were even normal. But, knowing my luck... it'd be my hearing that would sharpen :| and I'd get migrains from my cat purring at me.
