I can’t function without having at leased 300mg of dph in my system

I haven’t gone a day without using dph for over a month now and my brain fog has increased a lot and I'm out of breath all the time too, i’m still handling work good and I‘ve got a lot of money in saving right now so i‘m fine money wise but my dad is being a bitch to me saying that if he catches me high again he will kick me out, so that’s my life right now, pretty shit
