My son (now age 33) has ADHD, my other son (not with us anymore) had ADD and I was diagnosed with ADHD in 2006 (my family & I notice a change when my doctor got me on the right medicine).
My doctor 1st put me on Adderall but it was not staying with me & the higher dosage was bringing on one (1) of the big side effects, irritable with anger. I would talk to my doctor about it and we tried Concerta time release. I started out with 15mg 1x daily & 10mg 1x daily. That was not strong enough and he mored me to 20mg & 20mg. That worked but now I’m on 54mg 2x daily. Doing Great. You need to find the right medicine with the correct dosage.
