No wonder so many Moms tell me LCs are a hit or miss. Seems not even 'trained' LCs always know what they are talking about... If possible, search for IBCLCs - they have a more in depth knowledge, experience and well rounded idea on how best to help and express a realistic desire to help.
****If you were not drunk - it is still fine to breastfeed. Buzzing, feeling good, having 3-4 drinks - all fine. The body is an amazing system - - the Mother's body will filter thru most of the bad stuff (lack of proper nutrition, medications, alcohol, etc) and give the baby the best the Mother can offer thru her breastmilk.****
Most other nations breastfeed their children thru 3 years old, if not longer... do you REALLY think they give up drinking for that long? Nope... because their isn't a need. Excessive ANYTHING is bad, so if you are stumbling drunk, of course do not breastfeed... but if you just had enough to be feeling good and 'buzzed' feel safe knowing your body will handle the filtering of our breastmilk before the child gets it...
I am a child led weaning advocate. My daughter didn't completely wean herself until just recently, like June 2010 and she will be 5 in September.
