Hello dejavu, the only thing I have to add is that it will be helpful to observe the moods over a long period of time without changing medication too often because that can be very confusing. It's a good idea to keep a mood diary (you can download a blank chart off the Internet).
Your insight and ability to understand your body will be getting better and better, and along with the pdoc will definitely get you to something that works

A little patience - I know it's annoying, tiring, (the list can go on and on) but you will get there

And remember, the good days don't have to be bipolar high days, which after all is not a 'truthful' high

I wouldn't be afraid of a mood stabiliser if it turns out that's what you need...If it works properly it's not making you devoid of enthusiasm etc - just helps you regulate it and stops you from going insane!
Wish you the best
