I was tormented by doses that were just to low. I’m 53. Conservative and take it easy equals massive anxiety as I feel my life slip away. I finally got a doctor that explained and increased my dose. I hated it. But it worked. Regular old Ritalin extended release works best for me. Concerts with 5 mg methylphenidate in the morning or I would never get out of the circles. I don’t do anything until I know it’s kicked in because it’s so painful to know I just stumbled around and get frustrated. I’ve seen other people struggling with low doses as well. My body hurt, my self esteem suffered. I was stuck. The right dose makes depression and physical pain go away. I’m still swallowing hard as a person that didn’t want any chemicals in my body. But it works.
