Sleep apnea can be helped with the CPAP mask I think it's called (continuous positive airway pressure), basicly a posi-pressure breathing mask.
Often times the issue that causes the person to start to feel a choking or gasping sensation is the (I didn't do well in anatomy) flap of skin that droops down from the roof of the mouth, and the position of the tounge. Sometimes it can be "trimmed" to help prevent airflow from being blocked.
However Epilepsy and the need for the posi-pressure mask are two seperate issues. Most epileptics do NOT need to use the mask or need surgery on the roof of the mouth; thats a small percentage.
Side effects of medications may be another issue. Some medications make the person drowsy, others make sleep more difficult to come by. Medications can also disrupt eating pattern, cause hairloss, thicken hair, cause weight changes, emotional issues... the list goes on depending on the medication and dose. It all depends on the 1. Medication and 2. persons response to the medication (some respond better than others pending the medication)
It's a steep learning curve. A large library of information to read with a lot of new research continuing to come out every year.
