According to Wikipedia ….
A wave is a disturbance that propagates through space and time, usually with transference of energy. A mechanical wave is that which propagates through a medium due to the restoring forces it produces upon deformation. There also exist waves capable of traveling through vacuum, including electromagnetic radiation and probably gravitational radiation. Waves travel and transfer energy from one point to another, often with little or no permanent displacement of the particles of the medium (that is, with little or no associated mass transport); they consist instead of oscillations around almost fixed locations.

I’ve often used the WAVE metaphor as it relates to Irene’s experience with chronic, 24/7 nausea since June of 2007. We’re now using a 1-10 scale for me to better comprehend how debilitating the unrelenting nausea is at any particular moment.
WAVES are illustrative of Irene’s nausea experience. There are smaller waves, like a ripple, and there are colossal waves like the tidal wave. Irene’s nausea comes in random WAVES …. but the OCEAN OF NAUSEA is ever present, and the waves persist like a rising and lowering tide.
How she courageously faces this challenge with a buoyant attitude, strong faith and a smiling face are inarguable evidences of His enabling Holy Spirit.

Wikepedia’s WAVE description is very apropos: A wave is a disturbance that propagates through space and time, usually with transference of energy.
Irene’s experience with NAUSEA certainly fits that description but after facing it for nearly two years it is also in a category of its own. It’s difficult to truly grasp the reality of what Irene deals with 24/7.
