Hi Jennifer,
I've taken Inderal LA (long-acting) for about a year and a half. I take 80 mg in the morning, and 80 mg at night. It is part of my "cocktail" for anxiety.
It helps to keep the heart from being flooded with adrenaline. It is one of the meds that they would have to pry from my hands!

It really has helped sooo much with the physical symptoms of anxiety.
And like the other poster mentioned, when you don't feel your body freaking....you tend to not freak psychologically either!!
I wish you all the best. Like I said, I take 160 mg daily......which is actually lower than the dose used for migraines....and much lower than for its labelled use for blood pressure.
God bless,
Sandy
