I am not talking weight issues here but blood sugar issues. I could safely eat 3 pounds or so of potatoes with veggies and very minimal fat, without feeling like shit afterwords. But if I ever add fat, about one or so tsps, to "lower the glycemic index" it makes me feel shaky, sleepy, and very dizzy. Any idea why this happens? The idea to add fat to your carbs has never been good to me.

You mention that you think this is a blood sugar issue. Have you actually measured blood glucose with a meter? If you really think it is a blood sugar issue then I would recommend getting a meter and assessing what your blood sugar is doing.
There is an alternative possibility: there is bacterial activity in the gut as they feed on the potatoes, and the fat is carrying endotoxins into the body. When you shift from potatoes only (no fat to bring in endotoxins) to potatoes+fat, you get a surge of endotoxins and immune activity. The high immune activity clearing the toxins is what makes you feel bad.
Usually the gut adapts to this dietary change, releases antimicrobial peptides to reduce the gut bacterial population and tightens the gut barrier to reduce the endotoxin influx. So I would expect that the symptoms would be greatly reduced if you ate this way continuously for a few weeks.
You might want to try eating fermented vegetables, it's possible there's some mild gut dysbiosis at work and improving the gut flora might reduce the immune activity you see when fat and potatoes are eaten together.
You could also try including some rice, it's usually digested more fully than potatoes and leaves less fiber for the colon.

3 lbs of potatoes is quite a lot. That's over 200 grams of carbs, waaaay above what many people on Paleohacks who self-identify as moderate carbs eat (100 grams a day on Perfect Health Diet, less than 200 grams on Mark Sisson's plan).
Are you sure it's a blood sugar reaction too? Unless you are measuring your blood sugar, it can be hard to tell. What kind of fat are you adding? Have you tried different types of fat?

The problem with carbs is not that they 'turn to fat' because they usually don't, its that in the presence of high carbs dietary fat is stored. Carbs and fat at the same time is the worst combo of foods possible. Carbs+Protein or Fat+Protein are the best combos. IMO -- the shaky,sleepy,dizzy feeling could be from having jammed up the highway that is your blood.
