I liked not being hungry on it but could not in the end tolerate even a small dose because I started having trouble with word recall which was out of character for me. And later I found a better solution (actually, several of them) for the excessive hunger problem so no longer needed Topamax.
I have not tried taking it for mood.
I have tried it for migraines without success. Again, ultimately found a complete solution for migraines in the form of Nurtec.
