Ok... Im NOT suicidal AT ALL!!! Lets just nip that one in the bud right there!!

If I hypothetically (and I stress the word hypothetically - I've absolutely zero intention of doing this - Its just a curiosity!!) swallowed, say 20 - 30 piriton (chlorphenamine) tablets with a relatively large amount of alcohol (say a bottle of vodka or whatever)... would the combined sedative effect of both drugs slow my heart down to an eventual stop , or just induce a serious coma or would my body just realise its been poisoned & end up vomiting everything up????

Medical experts - show me what you know... Haha!!

Thanks!!
