Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.Temazepam
(Temaz) is a good drug to induce sleep with the only problem being its short duration of action. the effect normally wears off in 4 hours. The other good drug is zolpidem
which has action for 6-8 hours. however I am not sure of its availability at Peru.
Meanwhile try doing some relaxation exercises with controlled breathing and that may help.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
