Pain ratings and stress response will be measured via heart rate and blood pressure and salivary cortisol according to the study activities table below. No bloodspot kits will be collected during this visit. This study visit ends after the 270min post-induction blood draw. The PI will debrief subjects and assess their affective state. Free counseling will be offered before the subject leaves the study visit (only one person in the previous study opted for the post-study counseling). If anyone in the stress group would like a counseling referral the PI will provide local options to them. All participants receive a next-day telephone call to assess for mood state and adverse events.
