I am asking because in the morning I take 5mg of zoloft, 5mg concerta, and 600mg of seroquil 2 hours before bed. Recently I came upon an article about modafilin that seems like a promising occasional tool to help me in school. I do know the cost for the medication but I do prefer to have a little bit of info before i test it like if you have this medication you cant have this. as for why i take all these other meds is for ADD, PTSD, Anxiety, Depression and a few other things.
