I am prescribed Abilify and dexamphetamine and find that it does not aid in sleep. My doctor gives me clonidine to help sleep on the d-amp. When taking meth it has no noticeable affect on how high I am.
However, I find Abilify helps a lot on making your comedown easier - so it still has value. Best bet for getting sleep and crushing your comedown though is seroquel.
I think this comment was a while ago, but I'll toss in my two cents of experience anyway.
I was prescribed abilify partially to augment the antidepressant, Wellbutrin, and partially to counteract and quell some of the norepinephrine driven effects of wellbutrin--things like being very short tempered, it being hard and long to de-escalate and cool off once angry, and also obsessive ruminating over conflicts, irritations and resentments. Sometimes I would stay sore and combative even when a conflict had been appropriately resolved--like I couldn't be mollified or assuaged once incensed. It was terrible sometimes, and for me, like a Jekyll and Hyde transformation. By nature, I am usually very empathetic, reasonable, diplomatic to a fault and excel at conflict resolution and de-escalation. To be immodest, it is practically a superpower, but on wellbutrin, my personality is altered.
I actually feel Wellbutrin is a dangerous drug that people are not adequately warned about when it comes to its potential effects on temperament, rage, resentment and mistrust. Doctors wouldn't even admit it had this effect up until maybe five years ago. I have seen people go right batshit on wellbutrin, as though they were on a paranoid coked out aggressive binge. Abilify did work well for smoothing out these wound up, ragey fight/flight impacts of wellbutrin, but it made me bone tired all the time. I could take naps in between my naps and still konk out at night for 10-12 hours. It was a drugged out kind of tired feeling, hard to even resist it. I usually won't touch it now. I have read that it is a nasty antipsychotic that makes changes to your brain structure. I also found it largely inhibited or countered the effects of amphetamines. It is a dopamine agonist on some receptors, and dopamine antagonist on others.
Seroquel knocks me out like I was hit by a truck. I once took one that my housemate gave me and was not mindful of the dose--he is severely schizophrenic and his pharma regime would seriously put down a pack of elephants. The seroquel knocked me out for three days. I would briefly wake, but couldn't get my legs to function under me and then I'd just fall unconscious again. I'm a little leery of them now, but if I am having a hard time sleeping, I break one of them into quarters now.
Cocaine always gave me savage soul crushing come downs filled with choking anxiety, loathful shame, and deep dread inspired depression so severe It was hard to take a deep breath. To insulate from it, I would take opioids before a binge ended and often chase them with a gulped down bottle of liquor. That usually did the trick. Amps never bother me. Right now, I've been up five days on meth, which is quite excessive for me. This would be the comedown or crash time right now, but I just feel relaxed and pleasantly lazy. I am wholly grateful amps are not like cocaine for me.
