My husband and I consumed alcohol. Everything went well ; my husband had little more than me. When he got up in the morning ; he got unconscious for 2 times for 1-2 mins each. After that I realised may be his bp is low as he didn't eat anything after the drinks. He had last meal at 5pm and drinks at 9 pm and slept. This situation of unconsciousness was around 5 am in the morning and he wanted to puke that time. He didn't puke. After that I gave him food to eat. And he was normal, I got his bp,
sugar ecg checked around 8 am.
What could be the reason???
