protect your body with elbows and forearms.. slip, bob - weave to protect the head and parry shots with your glove. If you only keep double deck, thats limiting your boxing abilities..
btw, you really think that marijuana will ease pain from body punches?
Ease pain maybe yes because it is relaxing muscles and all that stuff but it wont PROTECT your body. So, if you take many body punishment, maybe its time to make your core/abs workout harder than before.
