My problem is the opposite. I can fall asleep very easily. Over 8 or 9 o'clock in the evening, if I'm doing something that doesn't require too much attention (like watching a film or something like that) I start to feel asleep and it's very hard not to.
The funny thing is that, if I let myself sleep for a few minutes (5-15), then I wake up fresh and ready to be awake a bunch of hours more (and it doesn't prevent me from getting asleep later).

You're essentially taking a nap and waking up before entering deep sleep. This is the refreshing kind of nap. Conversely sleeping just a few minutes more and waking up in the middle of deep sleep would make you feel grumpy and tired. There are some polyphasic sleep techniques that basically exploit this and have sveral short naps of light sleep throughout the 24 day instead of a night's sleep.
