Lisdexamfetamine
"I was diagnosed with ADD and my doctor recommended me to take vyvanse 40mg. The first day I took it around 6:00 am and it started to work about an hour in. I was able to focus very well and was a lot more sociable. However, the good effects of the medicine only lasted for 5 hours and then everything went downhill and I felt depressed. My heart was beating faster than usual, dry mouth, and had no desire for food. The next day thinking it would be better, it didn't kick in until around 2:00pm and only lasted for a few hours. Sometimes it would leave me feeling very antisocial and aggitated. Today is my last day taking it because it hasn't worked for me at all today. Wasn't hungry all day, felt very sweaty, nervous, aggitated, out of breathe."
