Smoking some Gawith Hoggarth Dark Flake Aromatic tonight and putting the pipe down for a bit since I'm noticing something peculiar. It seems whenever I smoke Dark Flake Aromatic or 1792 Flake I get a really bad headache, which is odd since I've smoked plenty of other strong blends like Kendal Dark, Dark Bird's Eye, Kendal Kentucky, Irish Flake, Nightcap, and so on and never gotten a headache from any of them; but both Dark Flake Aromatic and 1792 Flake give me a headache every time. I suspect it may be the Tonquin bean causing the headache, since those are the only two pipe blends I've ever smoked with Tonquin in them and also the only blends to ever give me a headache. Odd.
