Latuda, saphris, and abilify are all prohibitively expensive for me. I have a high deductible insurance plan so I pay for everything out of pocket until I hit it. Even at the discounted price abilify was $650 a month

! Even when I meet the deductible it was $60 per month. Way too much, and it didn't even help anyway.
I can't say I've ever been happy with an ap. They all have too many side effects for me to deal with, or they just don't do anything. I need one sometimes when an episode gets our of control but I prefer not to take them. So unfortunately I can't help you there! Butane backing off the lamictal will help. You can go back up if you get depressed.
