I'm sure everyone has had some level of discomfort from getting higher than they intended to. It is even worse when you have something important to do where you need to be capable of some concentration and memory.

Smoked a joint before my daughter's baptism and realized in the middle of the ceremony I was too stoned. Kind of too late then so I just went with it, but it was intense and not very enjoyable. My dad kept giving me weird looks as he conducted the ceremony, but he never said a word or let on to anyone else. That whole deal is on my life-list of stupid ideas.
