I experienced something weird. I felt that nothing is enjoyable anymore, everything is "boring," plus I was a little depressed. This was a horrible kind of feeling because literally nothing would work against it.
This is also very unusual for me as I never get bored, I can literally sit all by myself with nothing to do and be fine with it. Though I had not taken abilify in a long time so not sure if abilify could somehow be related to it. Maybe it was the slow-release melatonin I took. I know I react badly to melatonin.
Anyway, today I took abilify 5mg and felt literally nothing as if I had not taken it. Sometimes I can feel abilify but other times I cannot.
I have the opposite, without Abilify and when I just sit and do nothing I get depressed and at least (go force) myself to go for a work-out to chill. Now, with Abilify, I can just sit, be bored and do nothing at all without getting depressed by it. In your case Melantonin could be also contributing because of it's sedating effects. This has been my experience when adding a sedative: The past weekend I added 15mg Mirtazapine (and even though my sleep is still fragmented) I still got enough sleep in total. The downside, I'm taking a long acting "stimulant" (Abilify) + a long acting sedative (Mirtazapine). It's interacting/contradicting! The first week when I started Abilify I went off all drugs to see what the effects of Abilify on it's own would do, after going through terrible side-effects the first two days, I was fine the following days, although it provoked me into compulsive gambling (a known side-effect of Abilify) but even though I lost my loan I still felt relaxed, mellowed, positive symptom free + a strong antidepressant effect. Then I added 20mg Parnate, which seem to work synergistic with Abilify. Because my sleep was less and still fragmented, I added 50mg Trazadone, first two days I slept fairly well and still felt well (aside from increased anxiety, brain-fog and fragmented sleep), the third day I thought I like Abilify so much so I upped my dosage to 10mg, that's when the trouble started. Within 2 days I had some sort of "nervous break-down". Like I already said, I backed down to 5, then 2.5 and now since 2 days back to 5mg but I felt I had no other choice than adding 15mg Mirtazapine the past weekend. Last night I started having mild positive symptoms, took some extra Clonazepam and it resolved my issues. Last night I dropped the Mirtazapine to 7.5mg and added 25mg Promathazine in the hopes it would aid my fragmented sleep. This morning: waking up once 2 hours later after going to bed I could fall back to sleep easily, another 2 hours later and I was wide awake. I spent 4 hours in bed trying to fall a sleep but I just couldn't.
Anyway, before I get off-topic. It's the same with me on Abilify, one time I feel social/okay/chill/relaxed/optimistic/symptoms free, the other time unmotivated/apathetic/lethargic/anxious/paranoid/sluggish. One thing that last even though I feel crap right now, is it's antidepressant effect on me, I still can feel bored without my daily work-out which I hardly missed before Abilify. I think and it's just an idea/guess, I think Abilify is a first in class drug that has both agonist/antagonist properties that just was not well "designed" to be a stable drug (even though it was found effective enough to be marketed back in the days).
At this point I do not know what I will do. I have an appointment tomorrow with my pdoc and am going to ask for a short acting sleep-aid and maybe give Abilify another week. One thing is for sure, Abilify for me is temporary, once Cariprazine or (Abilify's successor) Brexpiprazole is on the market I'm off of it permanently.
