I'm type A also. I love to drink ACV in water, drink it everyday. Don't know about weight loss, as I am already thin. You should add several cups of green tea daily if you want to lose weight. But I haven't noticed any adverse reaction to ACV, if anything it must be good for me, anyway I crave it, and have more energy after I drink it. How about you do muscle testing, that way you'll know if it agrees with you personally.
