Does anyone use (for themselves or difficult child) GABA supplements? If so, please share your experience with this. My difficult child was on Depakote that worked beautifully for his irritability and lability, but had to go off when it elevated his blood ammonia level. Since Depakote raises GABA levels, I'm wondering if this would be a good option for him. Of course, I will discuss this with his psychiatrist, but wanted to get personal experiences here. Thanks!
