Benzos work for a lot of people, me included.
But I totally understand that a loss of control can be extremely scary. Because you do get drugged, especially at the beginning and if you're sensitive.
Benzos like Valium and Klonopin are much smoother and less druggy, especially Klonopin. Feeling drugged can really trigger strong anxiety.
For me the antihistamines made me feel so tired that my body interpreted it as shutting down, "it" thought it was dying. No wonder I got panic attacks.
