Portia, I tried GABA with our 3 year old but it has no effect on him, actually I think it made him even more anxious. But for ME it works like a charm!
DS3.6 has diagnosed Autism but we're pretty sure anxiety is affecting him more than anything else. We're waiting to get him evaluated officially for anxiety, hopefully soon (just got the script earlier this week).
I know hydroxyzine (strong antihistamine) is sometimes used to treat Anxiety but it hasn't worked on either of our boys. DS5.2 has it prescribed to help him with sleep but it's also used as anti-anxiety drug. But in his case it only makes him drowsy but no other effect.
