What are side affects of drinking alcohol while taking metronidazole vaginal gel. why can you not d?

Last night I thought I was going to die. I woke up in the middle of the night feeling very nauseous. I walked to the bathroom and I was forcing myself to throw up and I couldn't. I said I need milk because I drink milk before bed after I have a few drinks to prevent a hangover(not telling you to do it, it's something I do, consult with a doctor first before drinking milk after a few drinks). But, I couldn't get up! My legs felt locked! I started to sweat and shiver. My skin started to get cold and I started to see little dots and I knew if I get up right now, I would faint and hit myself on the corner of the sink or toilet. I yelled for my boyfriend's name to come. He said, what's wrong in a scared voice and I said get me milk, now, I can't get up. By then I'm uncontrollably sweating, and I'm panicking! I told my boyfriend, I think I need to go to the emergency room! I couldn't even cry, I was shocked, nauseous, sweating, laying flat on the bathroom floor. He got me a glass of milk, and I drank that glass so fast, I lost my breath for about 2 seconds. I laid back down and I asked for another glass. I'm still sweating, and seeing different colors. My vision started to blur and I told myself, Is this the feeling of when you're about to die? I have never felt this before so that's why I was determined that I was about to die. I mean, I was also woken up around 3:00am, your mind starts to play tricks on you. I asked for a cold towel as well. He placed the cold towel on my forehead, had another glass of milk. Few minutes passed, and I stopped sweating. My legs were tingly but I could lift them up, but I'm still laying flat on the floor. He got me a third glass of milk and I only drank half of it. I started to feel a tad better. Still nauseous but the blur vision, the constant sweating and feeling of fainting was slowly disappearing. I had the leftover milk on the glass right next to me. Just waiting a little more until I just felt nauseous. Believe me, I rather be nauseous than whatever I just felt. I drank the rest of the milk and crawled to bed. I didn't want to get up in a rush or even slowly because I was afraid of that feeling to return. I laid in bed, the nausea was also starting to go away but lingered a little more. I fell asleep. I woke up this morning not feeling 100 percent, more like 75-80 percent. Better than nothing. I can walk, sing and be myself again! Please don't drink alcohol with this medication. It was a terrible experience! If you do, call 911 thats the first thing to do or please have someone in the house, have milk and be prepared to to make a cold towel or ice pack to place on your forehead. Not sure if it was those three that helped. I'm not a doctor. Just a person who did a bad mistake of mixing metronidazole with alcohol.
