I've found that following those very same steps every single time leads to a perfect cup every time, no exceptions

I then add a single packet of splenda, stir really well (making sure to squish any lumps against the side of the mug to dissolve them thoroughly), and add a good amount of soy milk to turn it into a latte/mocha drink

If you're a chronic pain sufferer as i am and can't get as much exercise as other, non-injured people, that added fiber can be a godsend
