Honey and table sugar both contain glucose and fructose. Honey is monosaccharides, and table sugar is sucrose, which is fructose and glucose hooked together. Sucrose is broken down into glucose and fructose by the body. Chemically, they are not identical, but pretty close. Sugar is sugar is sugar regardless of the source.
Honey has 64 calories/tbspn and table sugar has 46. The advantage is that many people say honey is "sweeter" (fructose is sweeter than glucose, and honey has more fructose), and tend to use less of it than regular sugar. However, it sounds like you are getting an awful lot, and if you are using, say 1 1/2 tblspn honey on 4 pieces of toast, that is 6 tblspn, which is 256 empty calories.
If you use high fiber whole wheat bread, this is going to be more beneficial than say, wonderbread. Wonderbread has 110 calories/2slices, 3g fiber, 1g sugar, and 14g "other" (starches etc). (Four slices of high fiber bread is still a lot during the day, and you should probably focus the remainder of your daily carbs on vegetables)
Worst case then, (at 1 1/2tblspn honey per slice) you are getting over 696 extra calories per day, with little nutritional content, and 3g of fiber. Based on a 2000cal/day diet, this is nearly 1/3 of what you should eat each day, and meets much less than 1/3 of your nutritional needs. (Honey does have trace amounts of vitamins and minerals, as well as natural antibiotics. However, these amounts are negligible.)
The truth is, no added sugars contain many nutrients that are important for health. This is why highly sweetened products are referred to as "empty calories"
