Wow!! 2000 mg sounds like a crazy high dose! But what do I know! Glad to get some totally positive feedback!! So far today the lethargy seems a little better. My pdoc is sending me for labwork Monday to test my levels. She told me she plans to only treat the number if it is high as long as my moods are stable. I'm hoping they are but I had a little bit of a stepdown this afternoon in my mood. I'm just going to stay positive and believe it was just a tiny blip on the radar and hope it doesn't happen again. She seemed to imply that I would need a higher mg though. We shall see!! Thanks for the info newtothis31!!
