Yes I smoke it all at once. That being said, ALL is subjective. depending on the cigar, all could be 1/2 way 1/3 , 2/3 or I can smoke it till it burns my fingers. Every cigar seems to be different to me. I like the La Gloria Cubana Corona Gordas 6" x 52. Some days It gets bitter 1/2 way, some days after I burn my fingers I'll light another one up and keep smoking. When I started I was told, smoke it untill your not enjoying it any more. Then toss it. I have cut a few cigars, then relit them at a later date. I didn't like them, BUT, I've only been smoking cigars for 6-7 months now. Do a search, someone just did a post about re-lighting cigars. Hope this helps.
