"i felt very little positive effect when i was on 150 sr  for two months. after i switched to xl 300 i noticed a change. i have been taking this for about two months. all i can say is hang in there! for me the side effects were awful and it took so long to start feeling better. but now i do! i feel like myself again--i don&#039;t feel blissfully happy and i still get down at times but i feel like a normal human being. this quite literally saved my life."
