My 62 yr old husband was brought to hospital last night after bouts of laughing,crying, screaming.He was restring in 4 points {hard to see}, but after a dose of Haldol & Adderal(sp) he calmed cown & they released him.The Dr. could not explain,other than his lactic acid was sky high when brought ing & now it is normal.He is prone to panic attacks, bit this a whole symptom. Please help!!!
