How To Treat Vomiting Caused After Taking Citalopram With Alcohol?

I have been taking citalopram for about 8 months and last night I made the huge mistake of drinking liquor while on it. I blacked out and woke up this morning throwing up very foamy bile/fluid. I have been trying to sleep it off. Shld I be drinking lots of water or Gatorade? I hope this feeling goes away soon
