Hi my husband has weaned and come off keppra , after having only one sleep seizure. Since coming off, sleeping has been rough. Shallow breathing , gasping, twithching,and waking coughing , to a point can't get breath due to mucus in throat. Has no other symptoms of a cold etc. Not sure if need to assume it's due to coming off meds and brain activity at night causing shallow breathing , gasping twitching, coughing to the point can't breathe ??
