I threw up after eating for the first time in a couple days, is this normal?

I've never intentionally starved myself but being in college at the moment I'm often very busy and quite tight financially, so it's not uncommon for me to have a full day between meals. This morning I woke up to some serious hunger pangs (the last time I'd eaten was a little under 2 days before). I took a walk to the subway on campus and got a sandwich, but after eating about a quarter of it and having a couple sips of water I vomited it all back up. Granted I had been drinking the night before which likely irritated my system, but I've gone longer than this without eating before with no incident. Just making sure this isn't something to be concerned about. Also yes, I'm aware my eating habits are terrible for me and doing serious damage to my body. I'm working on fixing that

Well, nobody has to eat every 4 hours.  You fast longer than that every day during sleep.  Different people have different nutritional habits.  But intentionally fasting occasionally is one thing; to just not eat and then, during this false fast, to consume alcohol, is asking for death.  Alcoholics do this.  So the general tenor of joyful's post will hopefully get your attention.

Nothing about this is normal. Not eating for 2 days or even as long as 4 hours is highly unhealthy. This reads ED all over it or alcoholism if you're drinking and not eating.
