Well after suffering severe anxiety and panic attacks for over 40 years, there is little that I have not tried really. Atm, baclofen taken as needed has been a great help. I have cut down my antidepressants slowly by 50% and find valium makes me more agitated, so have rarely taken that.
I buy Melatonin from iherb, 10 mg pills, the 21st century brand. These are very effective and good value. Having recently struggled more with sleep issues I have been taking 20 mg with great results. When checking if this dose was too high, I came across a myriad of other conditions including cancer which showed promise.
