A really odd thing just happened to me. I've been working through a bullet of Paul Gotard Menthol Strong. This started out really light menthol (considering), similar to the same level I'd usually find in a Rockit Ice Cool. So pretty light, say a 2-3 out on a scale of 1-10, but not nose watering level of menthol. As I've progressed through the bullet I use I've found a bit of variance with some bumps being a bit stronger menthol than others.
The last bump I took from this bullet was a 11 on the 1-10 scale. Eyes watering, extreme pain, menthol so strong that I had snot free running from my nose for 3 minutes straight. No drip in the back of my throat, so not too strong of an intake.
Any ideas on what I did and advice on how to possibly avoid it in the future? TIA.
Edit: Tried a second bump. Back to being a 2-3 again, no burn, no crying. Could this just be a badly mixed batch?
