I don't think there IS a "BEST" bipolar med - what works for some, may not for others. There is no 'quick fix' for BP. It's not gonna happen overnight. It takes time and patience - trial and error - to find the right med combo for each person. Everyone's brain chemistry is different. (Therapy is invaluable, imho.)
Lithium literally saved my life - so I'm a wee bit prejudiced.
It's been around the longest - *possibly* more safe - because it's basically a naturally occurring substance - it's a salt.
Just *one* drug doesn't work for me. I'm on a 'cocktail' of sorts. Lithium stabilizes me, but I still need help with the depression + anxiety aspects of my BP.
Keep in mind that depression itself can cause weight gain and libido issues. Are you giving the meds enough of a chance?? Some drugs have temporary side-effects that diminish in a few weeks as your body adjusts to them. (I was 'stoned' for 3-4 weeks when I 1st started Lithium 5 yrs ago.)
Is it possible that your blurred vision is due to anxiety??
I was totally astonded to discover that's true for me.
I keep a running list of notes to take into my pdoc so I don't forget anything.
The best thing is to have a pdoc that you can TALK to, who can get to *know you* and work *with* you to get it all figured out.
Bright Blessings,
