This is the best decision I have ever made. Honestly It took about 3 weeks before I starting realizing the positive effects it had. So much more focus at work. I’m 62 and still work full time. I thought i was going to have to stop working due to my
Memory issues. This has changed my life. I am not worried any more about functioning at work. Just be diligent and use every day and give it time. You will not be disappointed.
