Hi Reddit,

Looking for some input on when I should bring up this topic. I smoke weed on a nightly basis to battle my (self-diagnosed/lifelong problem) insomnia. Without it, I get 2-3 hours of sleep maximum after tossing/turning for 5 hours.  With, I knock out after 30 minutes and am able to sleep 6+ hours.I admit that it also serves to wind me down, though this is not the purpose I began smoking. Rarely do I use it recreationally -- maybe once a month, about an hour earlier than I normally smoke before sleep).  My life and success have improved greatly after starting this remedy (GPA skyrocketed, landed a job in my field, etc.).

She hasn't explicitly spoken out against weed, however on our first or second date I asked if she's ever smoked anything. Her answer was no and the question wasn't returned to me.

Level of seriousness: We started dating 5 weeks ago and have seen each other every weekend since. We had sex twice last weekend and discussed/confirmed exclusivity, although we don't refer to each other as girlfriend/boyfriend quite yet. I can see us dating for quite a while, so I know this isn't something I want to hide from her forever.

Do I owe it to her to tell her immediately? She's coming over this weekend for our first full day/night over together.
Please advise!
<bot>: New relationship, smoke weed nightly to sleep, she doesn't touch the stuff.  When do I bring it up?
