I’m in my 40’s and have tried so many things to deal with my ADD! Adderall and Ritalin made it hard for me to sleep and if I missed a day or two, I felt almost like a crazy person, however going without my meds made it very difficult to function at work and causes me massive anxiety issues! I’ve learned over the years to implement a lot of behavior management techniques, a clean diet, numerous vitamin supplements and exercise to try ti replace my meds . It all did help a little but I would still deal with a lot of anxiety related to my ADD and nothing seemed to help with that! This supplement is the first thing that has ever worked for me without any negative side effects! On days I work, I take the full recommended dose but I find that on my days off I can take a half dose and that has been sufficient. It’s so wonderful to be able have all the positive effects of previous medications without dealing with the negative side effects. It’s also the first time in years that I haven’t dealt with anxiety related to my ADD or any of my other ADD symptoms! I’ve started recommending this to anyone I know who deals with ADD!
