Long one, ig. I just want advice.
I got diagnosed in 2020 and promptly put on prozac and olanzapine. I felt amazing!!! Literally have never felt that good and stable in my life. Plus, the combo managed to treat a lot of comorbids i was dealing with. 
It worked great for about 2 years until i realized i had put on about 40% of my previous body weight. Plus i had developed a tremor. So accounting for the fact that my insurance wouldnt cover symbyax (so i would have to take 2 separate prescriptions), plus i would need to add metformin to combat the weight, AND possibly add another to deal with the tremor, along with my adhd medication (in total, all of it would bring me up to 7 pills daily), i decided to try something else. 
So i have quite literally tried every bipolar medication auto covered by my insurance outside of lithium and others with similarly horrendous side effects. Annnnnd, nothing is comparing to olanzapine. Ive been on 150 mg of lamictal since july 14, and, hey, im stable and for the most part feel generally okay (except when i dont feel okay). In terms of mood swings, im having less rapid daily switching than even when i was on the olanzapine (7.5 mg) but i dont... feel as good, if that makes sense? Life is a little duller, my executive dysfunction is way down, anxiety and dissociation (though not constant, or even as often anymore) is up, my social life is shot, and my life now is just constant maladaptive daydreaming.
So, even though im stable, i think i need to change again. But i dont know like... how. I'm running with a few different options. 
1. I wait and let the current dose settle more and see how i feel in a month/try upping the dose to 200 mg/try upping my prozac dose and see what happens
2. Try and appeal to my insurance to cover latuda as a last ditch effort
3. Return to the olanzapine (appeal insurance to cover symbyax) and up the dose, return to taking the metformin, and play the tremors by ear

Like logically i understand i should try 1 and 2 first and then if those fail then i know i can always have 3 as a fall back plan.
The other thing im worrying about is... am i being greedy? Am i going to have an issue with every med i could possibly take? Should i just count my losses and return to the olanzapine because i know it works or should i settle for the lamictal because its side effect-free and, hey, at least im not spending my life savings and spontaneously moving across country.
Do i waste the next several months of my life trying to have it all or accept the situation.

(For further context, i never had a bipolar episode while on olanzapine. Or since ive started lamictal. So im figuring in terms of treating mood swings, both are similarly effective aside from overall... vibe... and side effects. I did have more daily ptsd swings on the olanzapine and those have decreased immensely on the lamictal, though dissociation is worse on the lamictal as well so... who tf knows.)
