Coffee

Amanda
Hello Ladies,
What are your takes on coffee during pregnancy. There is a number of websites that say a glass is okay. Well, I am nine weeks, and I gave into the craving. I used to drink multiple cups a day. As soon as I found out about being pregnant I quit cold turkey. I want to be as healthy and natural as possible. The last few weeks I the afternoon have been a huge struggle get through. I am exauhsted, to the point that I can not move. I am tired of feeling that way, not to mention how gawd awful my house looks, and being way too tired to exercise. I gave into a cup of joe this afternoon. And I feel FRIGGIN GREAT. No headaches, I cooked dinner, did laundry, and I simply feel normal, I even ate a meal!!!. Which is a far cry from what my afternoons normally look like. 
What do you think is it good? Is it bad? Have you been told?  I know it not the BEST, but either is being so lazy that you can't exercise.
I emailed my midwife to get her opinion, but I still want to know what other mothers experienced. 
Thank you for your opinions ahead of time.
