Like appearance wise, focus or attitude? I am going through some personal shit right now which I cannot discuss (Physical / mental), but these two help me sleep regularly everyday. I might end up taking both for a month on regular bases, but then I will quit. I was just wondering if the side effects would be hardly noticeable?. The reason why I'm on both is because I can't sacrifice sleep, I need to go to work and focus on my classes for the time being.
