I've been on Abilify for nearly 15 years in fact, I've been on the maximum prescribed dose for over a decade: 30mg/day.
I take mine at night after dinner and don't have much trouble sleeping. For almost all of this time, I've also been on an anti-depressant. But this past September I was switched from an AD to a mood stabilizer. Right now I take 100mg Lamictal and 30mg Abilify each night and do not have insomnia. I was a daily and nightly weed smoker for a decade as well and I don't think it interfered with the Abilify much but maybe the weed helped me sleep better. Either way, currently I only smoke bud once every two or three weeks and in the between times I'm straight. The absence of weed no longer affects my sleep but at first after quitting the daily toking, I had trouble sleeping. Long story short, is Abilify actually causing insomnia for you? It appeared to me in your original post that you are starting Abilify and only read somewhere that it causes insomnia.
Everyone reacts differently to these medications but Abilify has also been known to cause diabetes and it never caused that for me either. Just make sure you aren't inducing your own version of insomnia by obsessing over something that may not even be caused by the Abilify. If anything, the ADD medication would prolly cause insomnia more than an AP. But I'm not a doctor and this all should be discussed with your doctor, which it sounds like you are already doing.
OTOH, for the very short time I took Seroquel not only did I sleep very well at night, I was zapped of energy and was dead tired all day as well.
