S.O.
Have you taken it to your local pharmacy to get it flavored? I know those meds taste awful but maybe a little cherry or strawberry flavor will help. I know you can take it to Wal Mart and they will flavor it for a couple of bucks.
If you mix it in juice, just don't put it in orange or lemon juice. For some reason the acidity in those juices changes the effectiveness of some medications. So I was told to do apple or grape juice if I needed to mix in meds.
