doctor prescribed me Zanax for my anxiety for one time usage. She gave me a 0.5mg pill. I wasn't sure. But I tried less than a quarter or a pill around 7:30-8pm. I breastfeed. I knew my baby would sleep for at least six hours and that's how long she said to wait... before waking up but I went to sleep and then at 10:50pm my baby woke up. I fed him without truly taking a moment to think about the fact it had not been six hours. It was a tiny amount I took, I don't even really feel any side effects. However, I am almost in a state of panic. How couldn't I do this? My baby is 6 months old. What should I done
