Okay here I am about 13 weeks pregnant, wrangling a 3 year old and a 1 year old and I am simply exhausted.

I am getting plenty of sleep, taking my multivitamins and eating plenty of meat (I always crave meat when I am pregnant) so I know it isn't iron deficiency. My iron levels were tested when I first found I was pregnant and they were great.

But I am soooo lethargic. It's such an effort to function. I get tired just lugging DD from one room to another and I feel like I've got nothing in the tank. I think if the house was on fire I still couldn't bring myself to hurry!!! I just have no energy whatsoever.

What does help me feel more or less normal is one of those small cans of Coke (the 200ml ones). I am not thrilled about this...I haven't had much caffeine since DS was born and I found he was badly affected by it via breastfeeding...and I never got back into it. But now I am having one a day and I don't want this to continue.

I am thinking I need one of those green powder type of supplements - anyone taken these while pregnant? Are they okay in conjunction with a pregnancy multivitamin?

Any other tips?
