Yes, I would get horrible hypoglycemia "attacks" before going primal. There was one day when I didn't eat breakfast because we were going to Outback for lunch, and by the time we got there I couldn't even wait for them to bring the free bread - I had to eat a packet of sugar because I felt like I was going to pass out, was shaking, losing my peripheral vision (if you've had "episodes" I'm sure you know what I mean), all that.
I've done 24 hour fasts with no problem - might be something you have to build up to but eating LOTS of fat helps - if you have trouble fasting, take a look at what your last few meals before the fast were, and try to analyze it a bit. But even so, there's nothing wrong with an 18 hour fast, and I haven't done much more than 24-30 hours because I frankly like to eat. haha.
How much fat do you include in your meat + veggie meals? Are we talking poached chicken breasts, or thighs with skin-on, basted with bacon grease (hehe)? Or steaks topped with butter? Or lean pork cooked in a pan with little additional fat? - get some fat in/on the meat!
Same with the veggies - how you cook them makes a huge difference. Do you include lots of fat?
Protein+carbs do not make it easy to fast. Fat's the key for me.
(Dried fruit isn't the best snack as it's basically just sugar... try some chunks of cheddar cheese, or salami rolled up with cream cheese in it - get some fat in your snacks)
And I never get hypoglycemic episodes anymore.
