So it is normal to be on the low 4s then?
Not sure what type you are, but I'm a 1, my nutritionist told me my target is between 4.5 and 7.5, but to only eat if I go below 4 and even then only 20g of carbs, which is basically an extra small can of coke or 4 jelly babies... not much at all. I'm also currently on a treatment trial and they want me to keep good notes on levels and they only count a hypo at 3.5 or below... so don't worry till your lower then 4, and even though don't panic and over eat, but it's hard not to (I do it all the time, I'll sometimes have 4 jelly babies and a bar of chocolate... haha)
Hope that helps
