Recently I was out on generic Dexedrine 10mg er for adhd. Before being on this I was pretty normal, happy, no memory problems. But after taking this for a week I recently have felt a major brain fog, I'm also super depressed, unmotivated, and panicky. My memory is slow and so is my thinking and concentration. Everything is hazy and hard to remember. Do you think I need to seek medical help or will my brain go back to its normal state soon? Thanks.
