I smoke weed so that I can sleep at night.

I used to be incredibly fat, and even though I've lost over 100 lbs. I still have the heart palpitations that were a result from being so fat for so long. I am only 19 in college, and I could not sleep at night. For a while I just drank and partied a lot so I would just naturally pass out and sleep like that. Lately, I haven't been partying so much since I have a job, lacrosse practices and games, and am a volunteer firefighter. I go to the gym at least once a day and work out with a trainer. My doctor hasn't given me anything that has been able to stop the palpitations without giving me other side effects that I can't stand. A couple months ago, I started smoking weed occasionally, and over time I started smoking more and more with friends, at gatherings, whatever. I realized after a while that pot made it so that I could sleep easily and go to bed whenever I wanted, which was vital for me since I need to usually be up by 7 or 8. So, now I smoke weed every night, alone in my bathroom. I just feel weird that something I had never really done before is now such a prominent thing in my life. That is my confession.
