so i got a bunch of 15mg morphine immediate release last night, and i have a pretty high tolerance so i took 75mg and felt nothing! i think the prob was that 24 hrs b4 that i dosed 48mg of loperamide which can have blocking effects. a half hr ago, which has been bout 15 hrs after my 75mg dose last night, i took 90mg and it just hit me like a ton of bricks! should i be worried/ call 911 wit a dose like that of morph IR? very tingly, numb, and noticing slight shortness of breath which could just be anxiety, but the buzz keeps gettin stronger every minute. im also stuck at work and my boss is coming here in an hr!!! im freakin the fuck out! any help or advice would be greatly appreciated!
