I think recognising it is fairly easy. Being honest with yourself about it is the difficult bit.

I had an issue with withdrawing from pain killers after my accident and they completely kicked my arse. I'd broken the bag of withdrawal, but couldn't shake them completely. I still miss that feeling of haziness that clouds your head initially and then spreads slowly through your body.

In the end, I had to tell my sister what was up and go and stay at hers for a couple of weeks, just so I would be forced to go through the sweating and sleepless nights without having the easy way out. I was the master of telling myself that I'd do it tomorrow, then Friday would come and I'd promise that I'd definitely sort it on Monday.

People know what is going on, it just requires something extra to deal with it.
