Stop making shit up. There was no mention of narcolepsy. He is just fatigued from stimulant withdrawal.

Edit on re-reading I now realized an issue. He is not actually a taxi driver, that was a hallucination by the model. He works in a restaurant! That changes my evaluation of the situation quite a bit, as I thought he was at risk of being in an accident by falling asleep at the wheel. If he works in a restaurant muddling through the withdrawals seems like the right choice.

I think I got this misconception as I first read second-hand sources that quoted the taxi driver part without pointing out it was wrong, and only a close read was enough to dispel it.
