New Yorkers like things dark right - coffee, clothing, secluded bars?

Well, as I sit here in my bright blue sweater with my vibrant red coat slung over my chair, I've decided I'm not quite ready for this. Sure, I'll wear the dark clothing and bars of any sort are fun, but I can't drink my coffee black. PLEASE correct me if I'm wrong, but I think it is the cause of my morning vomits.

On Monday I got into work and made a cup of coffee. It was, "strong" coffee as my boss pointed out. There wasn't much sugar or cream in the office so the coffee went down black. About a half and hour later I was in the bathroom puking my guts out.

I figured it could be a few things - first day of work jitters (nah, probably not), bad coffee?, bad cream?, the fact that I didn't eat that morning (that wouldn't be the first time I had coffee on an empty stomach).

So now it's Friday and I made coffee again this morning. This time I bought the coffee myself, so it's good and fresh from Starbucks. I also brought in Splenda which I always use despite my boyfriend's efforts to switch me to the real thing. I didn't use any milk or cream though as we didn't have any here. So 30 minutes later I'm puking again. What gives?

I read some online blogs and commentary where people were saying they can't drink black coffee. Coffee is acidic and milk tends to help nutralize that. Maybe that's the issue. All I know is I'm a bit hesitant to down anything at this point.

Any advice?
