I have tried many kinds of ADHD medicines, but none worked for me. Recently I tried Adderall XR and it worked absolutely amazing. However, later I discovered something terrifying. I thought I took 2 pills of Adderall XR 10mg, but I just discovered that I have confused with 10mg and 30mg capsules and I have accidentally took 2 pills of 30mg that day when it was working very well. Today I took 20mg and there's no effect at all. Now it got me thinking maybe not that the ADHD medicines I tried before was not effective for me, but the dose I took was not high enough to show an effect. This is odd since my body is usually sensitive! Now I don't know what to do because I think 60mg everyday is a little too high, especially for a starting dose. Why does my body need such a large dose? Should I try other medicine?
