My 17 yr old son has tried several different medications and currently on Focalin XR. He started with 20mg and increased dose until 35 mg. When he took 35mg for a day he experienced increased heart rate, so it was reduced to 30mg. However, when it was reduced to 30mg, he said it was not great as when he was on 35mg. On 35mg he said he could get things much quicker and without much breaks.
I am wondering about how you know if you achieved the "sweet spot" with the medication. I feel he is not fully benefiting at 30mg but at the same time having little side effects versus 35mg with increased heart rate. I would love get some thought on this.
