Has anyone ever tried the honey and lemon diet?

Ok, so I was looking up the health properties of honey and found it had many uses. One was to drink it with warm water and lemon in the morning before breakfast. I have done so for two days and the combo has lifted my energy and spirits. I also found it helps a great deal with my work outs. I feel fantastic otherwise.
I am not taking anything else. I am eating wisely. And drinking plenty of water.
For some reason. I sometimes will feel my heart beating a bit weirdly. It doesn’t hurt. Just like a more forceful beat at odd times.
Its only occured since trying this. Is it a coincidence? Or does honey and lemon cause any erratic heart problems?
