Same here.. lost roughly 72 lbs. Made a world of difference. Read on...
About 6-1/2 years ago I was on tour in Costa Rica, our BL was a real piece of work.. stress was a daily thing. I was eating bad and drinking way too much beer already.. woke up one morning with tunnel vision and began to hyperventilate. I was taken to a pharmacy and had a BP of 220/170. Ended up in Jaco hospital for 8 hours, completely forgot all my high school Spanish and had the scariest day of my life - hooked to old school EKG machine, needles, exposed wires, cracked ceiling.. not to mention I missed my remaining gigs on the tour.
I had to wait a week for my BP to come down to fly home. I immediately quit drinking, went low sodium (stopped fast food, no more soda) and was put on heart meds. Within 8 months I was down 72 lbs and off the heart drugs... no alcohol since.
So yeah, it feels good to be more aerodynamic on stage and everything else that goes with it.
