Lately

For the past few days, I've been getting this thing where my left foot stumbles, and I feel disorientated just for a split-second. It happened a few times during yesterday and first thing this morning, and during the night when I needed to go down the corridor. It happened exactly like that immediately before some of my fits. I'll tell the neurologist about it when I see him next month. On which subject I'll need to contact the hospital to find out when the appointment is. I had a letter from them last December, but can't find it.
