Diazepam
"I started having panic attack, anxiety, which they all led me to insomnia for 4 days I was not able to sleep for more than 1.5hrs. I went to my GP and he prescribed me a dose of 7.5 mg of zopiclone  and this tablet acted very fast but only kept me a sleep for 3 hrs . My GP prescribed me 5 mg of diazepam for three days and when I took the first dose of 5 mg I waited and waited it just didn't do nothing and I had even more panic attacks and anxiety. So I decided to take all of them which makes 15mg  of diazepam and nothing happens just I felt like really confused and heavy headed after 6 hrs I managed to have some sleep for 8 hrs . I don't think this is the right medicine for me but next day it did make me feel calm and kind of relaxed."
