I did it in 1.54 hours with 3 basic sessions + 3 retouches. I went there after eating a banana , and a minute after getting hit, my head started spinning. I almost went crazy with hyperventilation and nausea. However, I recovered quickly thanks to the good post-processing. To be honest, I have several more to go. It's a little scary. Everyone, don't go on an empty stomach. Be sure to take something with you.
