I once woke up in an alley, seems I dosed too much vodka, I don't recommend vomiting for nutrient export.
Liquid carbon dosing is effective as long as you don't try and over do it. Solid carbon dosing is gaining in popularity, I have been using Bio-Pellets since June or July and you can over dose it as well. It is highly effective with proper dosing and testing. I suggest you do more research to determine if you want to begin doing that. It isn't for every tank, or everyone.
Oh...I have no horror stories from VSV, but with the BP I did watch my tank lose every form of algae, even my chaeto diminished. I did not have to clean my glass for months. I cut the BP quantity in half and things are doing much better. I don't mind a little algae.
