I take 800mg 4x a day. Some days I only take it 3x's, but I find taking it daily helps my "all over" pain. I definitely feel the difference if I don't take them. I've been on them for a little over a year. I did read withdrawls can be nasty if you try to stop using them. I will have to read more about
it though. For now, I will keep taking as prescribed.
I am one of the lucky ones...I don't get sleepy from them. Although, I am generally tired all the time...but I was that way before I started taking them.
