Any experience with mood stabilizers for ADHD?

I managed to get a final consultation with the psychiatrist that diagnosed me with ADHD (I’m switching to another cheaper practice). They suggested mood stabilizers as the most promising route, which also came up in my own personal research a couple months back after I have stopped taking any regular medication for ADHD or GAD.

I have been put on SSRIs (sertraline and citalopram), Stimulants (Lisdexamfetamine and long-acting methylphenidate), and non-stimulants (atomoxetine) from different doctors. I had been titrating ADHD medications concurrently with citalopram but stopped taking either a few months back.

All of them had mixed to negative results, in emotional instability, (low) mood changes, crashes, insomnia and/or physical side-effects (palpitations and other heart-related effects). Most are not manageable.

I’m becoming to learn that my symptoms face a sort of cyclicality, in which there are periods (day to day, week by week, but also season by season) where executive dysfunction and emotional dysregulation especially are more pronounced. This makes it difficult to manage my chronic illnesses, necessary day-to-day chores, and university.
