"i have had crippling lethargic depression. and was sleeping my whole life away. i have been taking methylphenidate for 8 years. i&#039;m very hyper. no bipolar but have had add, ptsd, depression and some hypomania. i think methylphenidate has helped me with all these symptoms. i can focus. do what needs to get done. clean my apartment. not sleep 24/7 anymore. i&#039;m calm. and have a much better life. more energy and i&#039;m happy!"
