Lamotrigine
"I am 26 years old & struggle with ADHD, PTSD, anxiety, an eating disorder, and dysthymia (bipolar type 2 now?). 
I always had impulse control issues and hypersensitive. Very irritable. Could go from laughing to crying in 20 seconds. 
I tried so hard my whole life to control my emotions and thoughts. Eventually self medicated with drugs. 
Finally decided to get sober and doctor said it be much easier if I stabilized my emotions so he recommended lamictal - because I refused to take any medications that make me gain weight. 

Lamictal changed my life. Don't get me wrong- I still get annoyed - but I can stop, think, and react calmly in a way that I just couldn't do before. I also don't cry over every little thing any more. Lamictal saved my life!"
