Hi everyone. I've been lurking in the shadows for awhile but have decided to finally show myself. I have a question about stimulants. My 13 yr old daughter is currently taking 15 mgs of adderall which works really well. The only problem is that she seems to metabolize it very quickly and she's benefiting from the medication for about 6 hours a day only. I'm sure a read here somewhere about splitting the dose and giving half in the morning and the other half mid day. Can anyone share their experience with this?
