Modafinil
"This medicine is literally a life changer. For so long I took adderall to get me through the day and to sustain focus during college courses. Adderall gave me severe anxiety and depression and I thought I had lost all hope seeing as that is "the best" drug for ADD... WRONG! Modafinil gives you the same level of focus without ANY side effects... no anxiety, no depression, no euphoria (which is great because adderall is very addictive) and minimal weight loss. It has improved my life to the point that my friends and family members have been commenting on how great I sound. I just wanted to share my experience (never have before, but I felt compelled to because this is an emotional topic for me) in case you're nervous about giving it a shot."
