so i tried oxy ther first time last year. shit was crazy first time i took a 40mg. I dont do this often just every now and then like once a month. usualy only need 1 or 2 perks to get a nice body buzz. so last night i take 1 and i get no buzz at all. i wake up this mornin and my backs hurtin and i take 1.5 and get no body buzz. so i take another 1.5 and still nothing. Im not sure if i got a immunity to them or wut, or maybe weed is having some sorta effect. any ideas?
