Hey there,
I wouldn't worry about an errection problem. If that does occur your endo doc can fix you up with some samples of viagra.
Yes, I too want to know if you are using a pump. And, 60 carbs in the morning is really nothing for a guy your size. I eat like 100 carbs or so in the morning and I am 5'5 at 145lbs. I am not that active as I work from home. But, you should know that oats take longer to digest and the sugar is not absorbed as quickly as other foods. So, if you notice two hours after eating breakfast, if your bg is not where it should be I would use your square or dual wave on your pump (assuming you have one) and use the 30 min or 1 hour option for oats related foods.
As for your work, I would say keep track of what you eat. I know it is a pain but right it down, even that wing or slice of toast
What this will do is see how much foods you are eating with high fats. If you eat high fat foods (esp at night) your blood sugars will be horrible for hours - unless you stay up late and monitor them. I know if I eat to much meat, like a nice double hamburger from my favorite fastfood joint, "culvers", I am going to pay for it for many hours. So, I dual wave it and sometimes even give myself a temp basal of 135% for several hours to keep the bg down. I can tell when I am getting low so I just turn the temp basal off. Watch the fatty foods at night. Pizza is another killer for me. I found that thin crusts helps though.
Like lancetchick said, get out another bottle of insulin and give it a whirl. And, if you are on the pump, check your reservoir to see if it has air bubbles in it. Mine does this all the time, the seals are not always 100%. And, check your site. 300 is not all that high for me, but, if it is anywhere near that after 2-3 hours, I will just give myself an injection as it gets into my blood stream quicker than the pump insulin (odd fact doc said).
Keep us informed.
