I had some time this morning so I did my situps, stretching a little weights. Had a cup of coffee, decided to take a vitamin and juice. Sat down at the computer with a second cup, and my mouth started to water, throat started to tighten. I ignored it for a few minutes and then thought OMG... I'm going to be sick! just made it to the bathroom in time. No photos tho - so not a pretty sight. it is true, you should not take a vitamin on an empty stomach with juice.
