Hello Julie,
Right mate so you was already on them...when your chipping your teeth at night is it through a seizure as you can do this through TMJ disease you know besides...the tongue lark is sore i bit across mine and cut it slightly open and the blood mate was terrible.
You maybe better off having one while asleep, the brain surgeon said nothing showed while awake...i kept awake all night and slept at the hospital why they ran the EEG and my brain apparently goes made with the electricity.
Long term memory with me is'nt to bad but short like yourself is bad and i don't think my right side not working through the brain damage helps as my left as to cope with seizures, foggyness everything involved where our processes need all the brain to try and function best possible.
Sod braingames i have enough coping...just watched an hour of OCD people on the box and some are doing it professional to earn money cleaning peoples homes :)
