I don't have problems sleeping and i do smoke daily most of the time (i shud'nt really cuz im only 15 and i think it'd be better if i only toked on weekend) but yea, i ussaly go bed about 12 and i ussaly fall asleep within half an hour. I acculy get tired really easy (without weed i mean). go bed about 12, wake up about 7:30 for school, and when i get bck from school i ussaly already feel very tired. But i ussaly don't go bed high, i ussaly go bed when the highs worn off and im burnt out. But most of the time i go bed without smokin anybud. Mybe you shud just toke in the daytime and avoid smoking before sleeping.
