What Causes Swollen Glands In Neck After Taking Tequila Shots?

My 37 year old daughter after a night of having a couple of tequila shots had the glands in her neck swell up almost immediately. She has felt tired since December but is normally very healthy. She has her own yoga studio and teaches and keeps very busy. She was thought to have Hodgkins at 14 years old but after a biopsy of her chest lymph glands it turned out to be Cat Scratch Disease. She is worried that this could be serious. Docs at minor care gave her an antibiotic and a virus blocker, what do you suggest?
