Try taking it at night when you want to get sleepy. It's actually great for having vivid dreams. Your doctor should have never started you on 600mg. You should have been started on 100 for one week then 200 for the second week etc etc. At one point a few months ago before all my operations I was on 900 to 1200mg a day. I would take 600mg after 10pm (I stay up late) and if I'm not asleep by 3am or so I take another 300mg. I had no problems functioning during the day. I was also told to take 400mg of Vitamin B2 everyday as well. This has helped my migraines a lot and also some other neurological pain I am having.
