Jon Gott -- the dude who chugged a full beer in the end zone after a touchdown in a CFL game last Friday -- says he played the rest of the night with a solid buzz ... and loved it!!!
You've seen the clip by now ... the Ottawa Redblacks OL ran straight to his girlfriend after his squad scored a TD late in the 3rd quarter -- and slammed some suds in epic fashion.
Well, Gott tells TMZ Sports all that booze had some consequences .
