M.H.
I am a nurse and deal with adults who won't take pills, or can't, on a regular basis. What we do for the adults who just don't want to (not adults with reason, but adults with dementia), is we put them in applesauce, sherbert, or ice cream. Dissolving them in large amounts of liquid would work if you knew she would coooperate and drink it all, otherwise you will not know how much she actually got. Best of luck and I hope that she gets to feeling better soon.
