My pdocs have told my that although Topamax is used off label as a mood stabilizer, it is a weak one, and it also has "an anti-depressant like quality." Whatever that means.

I'm glad that you are feeling "mellow." You have been hypo for quite a while.
When you say it's acting as an anti-depressant, do you mean that it's bringing you back down to earth? Or breaking the episode? Because Topamax, or any other mood stabilizer, can do that.

I wish you were sleeping better…
