bipolar disorde
"I took 100mg of XR and it worked pretty well to stabilize my bipolar tendencies. However, it made the whole world feel bland and neutral... nothing in my life felt particularly exciting or even depressing. Also, if I didn't sleep at least 10h per night, I would feel drowsy and out of it the next day. I was literally a walking zombie and waking up in the morning was a true battle. My doc told me that the tiredness would go away after a couple of weeks/months but after a little more than 7 months the effects were still the same so I stopped taking it."
