i havent tried the nectar stuff but to be honest, you should save your money and wait til after surgery to try things. what you may taste and like now, you most probably will not like post-op. i made a HUGE mistake ordering cases of stuff i ended up throwing away.
you can order samples from some of these sites. some are free and some are low cost. it's better to do that rather than buy a huge tub of something. this stuff is NOT cheap! lol. good luck
