We give our dogs lorazepam - dog valium. Get it from the vet. Problem solved.
I've taken Xanax for over 20 years. I have two choices. Seizure or take the pill. I had a cousin who did 2 tours in Nam. He came back OK or as good as anyone could have. He eventually retired at his 20 year mark in about 1980. He got a job and everything seemed to be going fine till the mid 1990's and he started having trouble with sounds bothering him. He underwent many test like I did all negative. Finally he went to a semi retired GP. The GP asked questions. Did you have ear issues as a child like tubes or ear infections? He said yes. Did you go to Nam? He said yes. Did you wear hearing protection? He said how could you? Doctor checked a few more minutes and said I know what's wrong. You have Inner Ear Damage from childhood and Nam. I can't cure it but I can treat it. His wasn't as severe as mine. But he spent thousands of dollars on testing.
Part of what has happened is the ability to filter noises is damaged. The dripping faucet when your trying to sleep thing. Noises sound louder at first than what they are. In my case the damage is so severe I have seizures from noises. I can also be visually triggered.
It's not a matter of it's in your head move on as some would like to think it is. It's neurological damage that has to be understood to live with it. It can begin many years after the damage is initially done and stress seems to be the what finally sets it off.
