I take alprazolam and when I first started this fight back into the world my doctor told me to take half a one with me (in the script bottle of course) and when the attack would start to put it under my tongue. It would then go very quickly into the bloodstream and directly to the brain. Please ask your doctor if the valium would work the same way before you try it and be aware it will taste awful.
Also have you made sure the valium your taking is gluten free? Here one dentist kept giving me the generic form, or tryed to anyway, and it wasn't gluten-free. Only the name brand was but it was very expensive. That's why my shrink uses the alprazolam for me, in that case the name brand, Xanax is not gluten free but the generic is. If you have gluten issues the Valium may help with the symptoms when you take it but if it is a form that is not gluten free it will keep the process going.
