My friend wants to know if it's okay for her to indulge in a can of coke each day? her cravings are so bad that if she doesnt drink it, she feels like she's going mad.

Maybe she can reduce to half a can a day if the craving is that bad but like what Juliana said, there is actually a risk to gestational diabetes and she won't want to go there. I had it and i had to take blood test on my own 7 times a day till i give birth to make sure my sugar level is in the healthy range.
