I also have been taking gnc mega women's but only for 3 days and i have been a zombie. I use to take centrum for womens and that made me tired but not as bad as the gnc ones. I was going nuts thinking i had mono or something. I am gonna quite taking a multivitamin altogether for a few days to see if i feel better. I also take fish oil but i am going to continue to take that. wow i am so glad i found this site. What a relieve! Do any of you think the tiredness would go away after our bodies get use to it? The guy at gnc said they take about a week to start working.
