"i suffer from dysthymic depression and had been on prozac until it stopped working and i started having suicidal thoughts. i&#039;ve been on pristiq for 3 months and it has changed my life for the better. i take it in the morning so i sleep at night. i am no longer tired. i have tons of energy and have a zest for living again. i have dropped 12 lbs and it does not affect my energy levels for running, biking and weight training. i can focus better at work and my sex drive has returned after being dulled for the past 7 years. my husband is thrilled. this drug has been a positive step for me."
