I am having problems sleeping. I used to smoke marijuana and for the longest time it help aid me to sleep at night and feel rested in the morning. due to legalities with marijuana and the fact it stopped helping sleep and started giving slight anxiety and keeping me up instead I stopped its use. I have tried melatonin using more then directed and it does absolutely nothing to me after the first use. I have tried all over counter sleep aids and other over counter drugs that cause drowsiness but they either don t work after the first few times of using even taking more then recommend and some sleep aids caused major anxiety. my doctor had prescribed me anti depressants that once again worked at first but had major nervous system side affects and once again didn t work after few days use. is there a reason for the quick tolerance build up to everything I take and is there anything that would work for me and my problem with having anxiety side effect with drugs that should cause drowsiness. I am desperate to sleep and not feel tired throughout the day time and wide awake at night. if you have any knowledge of anything that would help I would appreciate it.
