When I smoke a heavy nicotine bomb, like Nightcap, Cotton Boll, or Picayune, I like to have those nibbler sized chocolates next to my chair. The nicotine makes your sugar drop and that's what causes most of the lightheaded-ness. So, when I smoke one of those, I will nibble on a small Hershey bar or something like it. Sometimes in the dead of winter I will also have a warm glass of apricot juice with a dash of cinnamon to accompany my smoke also.
I don't usually eat while smoking. Just sip on water usually.
If I'm having a blend with a bit of kick to it nicotine wise I will make sure to have a snack/meal before having the bowl. Nothing routine about it though, just something to absorb the punch of lady N.
Smoking a pipe is not reserved as a special moment in my day. If it's time to eat I eat. Time to work? I works. With evening pipes I sometimes look forward to glass of something but I'm done eating by that time. Oh! Oh! Forgot popcorn or possibly a bit of ice cream late in the evening if I get a craving. Still, no conscious pairing of snack and pipe.
Solid food and pipe smoke don't pair well for me. They are separate pleasures. I grew up eating three big meals a day and never snacked much. In boot camp, this was a plus because hoarding snacks in your clothes was considered a big breach of discipline. Now I am under commandments to eat regular snacks to avoid diabetes, healthful snacks. I like beverages with a pipe, but more tea hot or cold, occasionally bourbon, water. Not so much coffee, beer, or milk which I find coat my mouth too much. But boy, this is so much a personal thing. One man's delight is another man's (woman's) misery.
I'm also in the camp of not enjoying eating when I smoke. I don't like extra salivation, and I feel like bits of food just don't mix with the pipe. Also, even though I drink while smoking (water, tea, coffee, whiskey, beer, whatever) somehow I feel like drinks cleanse the palate and add to the tobacco flavor, while eating somehow takes away. Probably just a personal feeling but, there you have it.
