Eating something light
"Having something light to eat so your stomach is not empty is generally considered a good idea. The chance of reflex vomiting brought on by drinking the bitter Nembutal liquid is reduced if there is something in the stomach. This should not be a significant meal that will slow the absorption of the drug. Something light is preferable, like tea and toast, an hour or so before taking the drug."

Drinking Alcohol after the Nembutal
"The liquid in the glass can be drunk quickly in 2 or 3 swallows, and then followed by some alcohol, usually spirits or liqueur. Although not essential, alcohol is recommended as it alleviates the bitter Nembutal after-taste, and will speed the drug's action."

Mixing Nembutal with something Else to take away the Bitter Taste
"It is always better to take one's Nembutal straight. The likely result of mixing the Nembutal with something else (eg. yogurt) is the creation of a greater volume of an equally unpalatable substance. Furthermore, using a spoon to consume the drug, rather than drinking it, can mean a longer time to ingest the 100ml.
"Exit has received reports of people falling asleep before all of the drug is consumed. This is dangerous. It is best to drink the 100ml in a few swallows, then drink alcohol."
