‘Start to fade’ is a good description. If I attend a social event, either of 2 things can happen. Either I start to fade when everyone else is still raring to go or I don’t fade at all, but when I get home and go to bed the adrenaline is still coursing through my veins and I can’t switch off and go to sleep, so I’m exhausted the next day. The worst thing is if I try to carry on once I’ve ‘faded’. I know that I’m really hammering myself if I do that.
I can’t rest or sleep during the day, as if I do, I can’t get going again and feel sluggish for the rest of the day. I have to take my time in the morning and then keep going for the limited number of hours left until it’s time for bed.
