It will pass..i used to drinks lots of sodas and did drink espresso drinks .. along time ago .. like about 5-6 years ago. You get over it quickly and then when you do have a caffeinated soda again or coffee again .. well for me .. it gets me soo jittery and SOO SICK and terrible and I get a headache ...oh and awful stomach crams drinking coffee. Its awful. So I stay away! Well I just started drink the caffine free stuff .. for awhile there .. every now and then..before I started LowCarbing.

You'll be ok pretty soon.
