wakeful

Why I must have been dropping off to sleep, too, and it startled me into wakefulness.

The houses had no wakefulness, they were but seen to stand, and the light was a revelation of emptiness.

Wakefulness caused by neuralgic pains, or by exhaustion, often yields readily to scruple doses of valerianate of zinc or ammonia.

Repose thus obtained in the daytime often serves to convert the night into a season of wakefulness.
