You need to use grapes in a hot kind of meal to salve those nerves, grapes move well internally and soups are good for making it warm in there (no shrimp based ones), and there's also using chocolate pudding if you vape. That would make it easy to move the chocolate over the nerves while the tobacco and smokeish move around the body stimulating the lungs as what tobacco does.
Medication? Dont take what they gave you. If you made them feel threatened, they are legally allowed to poison you to switch the hospital without notifying you. Gabapentin is for mouth pains while using aspirin.
Otherwise, weed does the trick at low doses, one bong rip a day, or two. No vape after, vape before and then an hour later.
Valium before vaping, one a week or in a controlled dosage, lowered amount that is taken orally prior to smoking/vaping, will clean that foul and move it to the throat and arms where simple exercise can beat those demon nerves. And then a lengthy diet, like a new favorite food, of milk with sugar in it should help the nerves feel less like syringes.
No chicken or pork and you should be good as new after about 2 months. Never to be bothered by it again
