Coma
The drowsiness and sleepiness usually gradually develops into a phase where people become unconscious and can’t respond at all to anything around them. You may seem to be peacefully asleep or may move, twitch or grimace occasionally as though you are dreaming. Although you will not be able to respond to the people around you at this time it is likely that you will be aware that they are there. It is likely that you will be able to hear them if they talk to you. This phase may last only a few hours or can continue for a few days.
At this stage, food and drink are not necessary, as your body is no longer able to absorb or use them. Moistening your lips or mouth are all that is needed. Once a person stops drinking they usually only live for a few days.
