Measure
Caffeine Arm
Experimental Group: patient group (n = 34) receiving a 100 mg dose of caffeine (1/2 of a 200mg tablet to be taken whole or crushed), taken twice daily. This will be an adjuvant to their standard pain control. Caffeine Tablet: Caffeine is approved by the FDA as a stimulant. A stimulant approved by the United States Food and Drug Administration (FDA) for the treatment to increase mental alertness and in combination with painkiller to treat migraine headaches. It is approved in the form of pill or tablet.
Placebo Arm
Control group: patient group (n = 34) receiving placebo compounded to look similar to the caffeine treatment, taken twice daily. This will be an adjuvant to their standard pain control. Caffeine Tablet: Caffeine is approved by the FDA as a stimulant. A stimulant approved by the United States Food and Drug Administration (FDA) for the treatment to increase mental alertness and in combination with painkiller to treat migraine headaches. It is approved in the form of pill or tablet. Placebo: Placebo, empty opaque dark blue blank capsule, taken twice daily. This will be an adjuvant to their standard pain control.
