I was on the 15mg pill and had really no side effects other than when I first started it. I had some akathesia for about a week, but it died off and had no other issues. I take it with Zonegran & Lamictal and (Seroquel) for sleep. But with the two mood stabilizers + the Abilify it was great. I had lots of energy, I loved life and all that junk. Oh I still love life and I'm still on all those meds and nothing changed dosage or anything other than Abilify, I'm now on the once per month injection. I'm also losing weight on it! I'm losing 5-6lbs every 2 weeks on it. That is awesome! Keep positive about it, I love it.
