Marijuna cured my severe Insomnia

I live in Canada were a possession of a few joints for personal use will not result in a criminal record but a fine (New Law ). My regular doctor works for a clinic run by an hospital.I always have suffered from insonmia but nothing like the last few months .My normal cycle lately is to stay awake all night for 3 nights and then collapse from exaustion on the fourth night .My regular doctor does not believe In prescribing Benzodiazepines like ativan,halcion ,or valium ,etc. I have bugged my doctor about insomnia for a long time.He suggested drugs like seroquel for Insomnia.Seroquel (100 mg ) . Seroquel , in larger dosages, is used to treat schyzophrenics , who see demons in their rooms ,hear voices ,think they are God ,etc .I suffer none of the delusions as previously listed . Seroquel works well for insomnia ,but turns you into vegetable. You lose the ability to cocentrate as far reading technical books ,following the plot of a " Agatha Christie " like movies .I was reduced to watching the cartoon channel. I can't stand seroquel,and have stopped taking it. A friend who smokes the odd couple of joints on the weekends GAVE me me 2 joints. I smoked both of them already . In each case I felt my legs go rubbery,and I went to bed and slept like a baby for about 6 hours. Last night I woke up and felt very hungry , I ordered a pizza from a late night pizza store. Years ago ,Hacion (2 pills ,0.25mg each )worked very well,but now , no doctor will prescribe it anymore, I tried several docs . Question : Why the bias against halcion ?I still believe that somebody that drinks or smokes sugar and drives a car after should be charged fully by the police.What's is your advice ? Peace to all , terence
