Coffee - and my love&hate relationship

Love;
Because it is a brilliant social beverage. As soon as I think about meeting up for a chat with someone, I think about cappuchino down town. And sometimes I actually start in this latter end, I think about cappuchino down town, and then ask myself "who can I meet up with?".
The smell is absolutely wonderful, both as the roasted bean and as a finished boiled product. At least nowadays. Because it was only 2 years ago that I started drinking coffee at all. Before I loved the smell of roasted coffee beans, but I could not stand the bitterness of the drink. Then a colleague of mine convinced me to just try to start, and I tried, and I got hooked. Now, I don't mean hooked in a regular "coffee hooked"-fashion, like normal people are I guess; drinking coffee a few times a day. But more in this way that I can think about coffee, wondering when I can drink it next time.

Hate;
Because it too many times gives me ridiculously side effects and flaring up, from just drinking one innocent cup of coffee+milk or cappuchino; rapidly beating heart, cold sweat, nausea, dizziness, and like now - inability to sleep properly up to 10 hours after a single cup.

We were out for a delayed celebration of my mum's 50th birthday yesterday. We went to an absolutely lovely place called Wine and Tapas, here in Lund. We ate lots of nice food, had some wine, my mum opened some gifts, and after all this we still weren't satisfied. We decided to go for dessert. I had a lovely white chocolate mousse with mango puré. Now, in my defence, I usually don't like white chocolate, but this was rather lovely I must say. Anyway, this was nowhere near the point of this section. Alongside my chocolate mousse, I decided to go for a lovely cappuchino. It was excellent, just excellent. Bitter, fluffy, warm, and just... just lovely. The coffee intake was limited to between 9.30 and 10 pm.

And here I am, at least no rapidly beating heart or anything like that, but just a general nausea feeling, and having slept ever so lightly for about 4.5h, and now, not being able to go back to sleep again. And it is only 5 am, this is way too early to wake up. The tricky thing is that I am very very tired. I worked very hard yesterday, got up early, worked for 8.5h (despite my 50% sick leave), then went out for that social event all evening, and not going to bed until after midnight. But however much yawning I do, and however much sleepy I feel - I cannot sleep.

And I blame it all on coffee.
