"as i&#039;ve only been on the medication a week, don&#039;t take this review exactly to heart. my first day on this medication was extremely brain foggy, trouble concentrating and very sleepy. i was already sleeping excessively to begin with, which is something i was needing help with. the first night i took this i slept for 14 hours, which is actually way more then i usually do. i also didn&#039;t really feel like myself taking this medication, it kinda sucks the life right out of you. i would reply slower to things, take longer to think of responses, and all in all lack the normal enthusiasm i usually had. now, as far as my mood swings went, i believe i have a mild case of bipolar. my doctor prescribed me 200 mg twice a day, which i&#039;ve just been halfing"
