I don't know about it, but with doing Atkins they recommend that you eat every 4-6 hours maximum to avoid a blood sugar crash, since you are maintaining low levels.
If the condition really is a problem for you, then I think Empress is right, eating smaller meals more often during the day might even out your sugar levels so that you can maintain a constant energy. You might play around with eating as often as every 2-3 hours during the day. All day tapas, anyone? :D

edit: To do low sugar diets like Atkins and the low GI diet, you have to become familiar with roughly the sugar contents of the carbs you do consume, mainly low GI veggies and some low GI fruits. I do have the atkins book and I sometimes look up the carb contents of various foods to refresh my memory. No, I don't know exact amounts, I know for example, that a serving of blackberries is better for me than an orange, purely from a sugar/fiber standpoint. And blackberries are better even than strawberries and blueberries for that. You can read about the Atkins diet online for for free, here:

Total grams of sugar/serving - fiber content = countable carbs for that serving of food. In the case of blackberries:
0.25 cup Blackberries
4.6 Total carbs
1.9 Fiber
2.7 Net countable carbs
http://www.atkins.com/Program/FourPhases/CarbCounter/Details13/Fruits.aspxKnowing that, you can decide how many or how few blackberries you want to eat. A 1/4 C? A 1/2 C? A full C? It's up to you, just be aware of how many carbs you are consuming for that item.
