my 8 year old daughter has just recentenly started taking Metformin. I was wondering if it is normal for her to be so quiet? She normally is very not this quiet. I have had a hard time taking giving her her med as it is an oral solution and has a horrible taste. I have been putting it in her choc milk to get her to drink it. Any other suggestions? I also noticed if she doesnt get it right away she is very crabby and irritable
