I'm still new to pipe smoking but I thought I was getting a little better at it...until this morning. I just received a new pipe in the mail yesterday with some good tobacco to go with it. I bought a Stanwell Featherweight 243 and a few tins of tobacco, one of them Dunhill Flake. I've recently been experimenting with flakes as I have found aromatics a bit of a let down. This wasn't my first go with a flake. I bought some Orlik Golden Sliced a few months ago and the first time I smoked it it burnt the hell out of my mouth, throat, and tongue. I went back to it a few weeks ago and everything seemed to be ok. Last night I packed my Stanwell with the Dunhill Flake, fully rubbed out, and had what I thought was a pretty enjoyable smoke. However, when I woke up today I felt horrible. Sore throat, headache, etc. All day I felt like I had a terrible hangover. You know the kind after you go out drinking all night and smoke a whole pack of cigarettes? The only thing is I didn't drink any alcohol or smoke any cigs.I don't inhale pipe smoke either. I'm just not sure what went wrong. Advice would be surely appreciated. Thanks.
