I have been going to the dental school. Cheap on prices but slow on time. Often Im in the chair 3 hours at a time. Cant do my lozenges then. Im about going bat crazy by the time I leave. Thank god for nitrous.Two hours is about my limit. I don't get anxiety; I get lethargic, sleepy, or just generally cranky depending on the circumstances.
If know I'm going to be spending time someplace I can't vape, something which is quite rare, nicotine gum is my friend.
