You should try Melatonin supplements and/or antihistamines - they should not require perscription and they are perfectly safe.
Your body makes melatonin as a part of the inner clock mechanism, at night/in darkness. Antihistamines is meant to counter histamines when you have allergies or something.
Both will make you drowsy and might help, without putting a perscription drug in your system to take over the function of inducing sleep.
I too am not very happy with doctors, the majority of will take over the conversation and you won't get a clear answer to what exactly a drug does to you for example. It helps to be super straightforward though, or get a better doctor.
