Powerdrive and Education

About to start college, at doctorate level in October aged 50. I suspect I will suffer from an inability to focus having not been a student for 20 years. What experience have you all had using Powerdrive for this purpose. If successful, what protocol did you follow?
Thanks in advance - John

Just trying to get a reply guys and gals. John

This was discussed in detail a week or two ago. Try the search engine. Look for “Power Drive”- - two words. Long story short- everyone seems to love it for studying and class. Take no more than twice per day, some add a caffeine tablet for boring classes or early morning classes. Great product.
