if you are pregnant and drinking heavily i'm going to suggest an urgent gynae appointment where you discuss this with your doctor. i'm not judging you - but you need to be honest with your doctor about this.
you say you just came off a 5 day binge. what's your plan for not picking up a drink once you feel physically better? i couldn't go an hour without a drink at my worst - i'm nearly 9 months sober and if i can do it, you can, but it takes work. i'm not even remotely out of the woods in terms of sober time, but it feels genuinely awesome.
there is life without alcohol. i promise. but you must please see a doctor, and come up with a plan for at least the remainder of your pregnancy.
please, please be well.
