Seizures
"On phenobarbital from age of 2 to 8, because I passed out in the high chair, probably hyperventilated.  I was giving dose before bed every night. I couldn&#039;t fall asleep till nearly morning.  As an adult,  on meth for 20 years. I don&#039;t know if there is a connection or not, but no one else in my family is an addict. I don&#039;t mean to whine, just telling my experience."
