Take wellbutrin as it is prescribed to be taken - every day. Then make a judgement about whether it works, rather than creating a half idea that it doesn't work, but you didn't give it a chance to, but you would like to try something else because the new drug might work better.
I am not trying to be nasty but you are need to think about what you are doing and what you expect to get out of the drug. SSRI's aren't candy and can have nasty side effects, so it is best to minimize experimenting.
I took Abilify as an adjunct to Effexor XR about two years ago. It made me have restless leg syndrome. It may not affect you that way. Everyone is different. If you're going to try it, make sure you're consistent about taking your meds. They can't work if you don't take them as they're prescribed. I don't mean to preach to you, but you know what I'm saying is true. Good luck if you try Abilify. I hope it works for you.
Peace and many blessings,
