This spray... is freakishly amazing! I forgot to eat before my appointment, shame on me. I unfortunately got the uncontrollable shakes, my blood sugar was super low, ugh embarrassing! BUT! I legit felt NOTHING, I was trying to focus and feel where the needle was and I legit couldn't feel a thing! Got me through my final hour and a half when my body was literally shutting down. I will forever be a customer of these products. Insanely good!
