Hey ladies,
I'm just wondering what you take for constipation? I'm someone who suffers constipation anyway but I think the elevit I take makes it 10x worse. My doctor recommended that I take Metamucil... which hasn't done anything. I'm craving fruit so I'm eating lots of fruit anyway, I drink about 2-2.5 litres water a day and I still haven't had a bowel movement in three days.... it's becoming painful.
