We are going through this now.
She gets "soda" in between sips of the medicine, to help with the taste, and also candy.
Every other try led to her spitting it back out at us, or not drinking it quick enough in the juice.
We also had the pharmacy flavor it, in hopes that would help.
It has been stressful since she never gave us issues when giving her tylenol or any other meds in the paste, so part of me thinks its a phase too.
