I'm going to get a brazilian bikini wax this week. What can I do to lessen the pain besides taking two Advils?

well, besides taking some pain relievers, make sure it is not the week before your period. for some women this time makes you especially sensitive to anything that might inflict pain. and please try to stay calm, tensing your muscles and being overly worried can intensify pain that would ordinarily be tolerable. and if you feel comfortable, ask if a close friend can accompany you so you have someone to talk to to divert your attention. and make sure your waxer is accredited and well trained, you never know nowadays. hope this helps.
