Royals,
When trying any new scents or mones, you can get a headache from them as I have and sometimes do. I would say ease into it with maybe just one spray and as you get accustomed to it up the spray to two. It’s not really fun if it’s giving you a headache.
As for being able to give people a hit in class, yes you actually can. It’s usually one of those things where the person next to you, in front or behind you (in your near area) keeps fidgeting or looking around.
I’d recommend taking a quick read through How to Apply the Pheromones?Best places
?HITS? and how to get them (How do I know if I am getting hits !!)
What Pheromones Can Do And What They Can’t Do
These quick reads will help you in understanding some of the works.
Maybe take a day break from the phermones and try again on another day when you are more rested. I should also mention, it takes using the product for more than the one time to allow you to be more comfortable and possibly extrovert. This is not a quick evolution. If you can simply try to enjoy the level of comfort you a growing into on a day to day basis. (What pheromones can and can't do: realistic expectations for newcomers)
