is 7 , 10 , 12 large doses of humolog insulin ? compared to 16 of levimir i hate the fact i dont understand my levimir im not entirly sure what a basal insulin does really its a nightmare this morning i woke up with a blood sugar of 4.3 then took 7 units of humlog ate about 40g of carbs and then a hour later my blood was 1.2 i didnt feel this i might add until i started getting a slight headache then my blood sugar now after correcting the hypo is 12.5 see how my days are playing out regularly this has been going on for a year and a half now so its a nightmare
Your waking blood sugar is good. Perfect even. But wow! 7 units for 40g carb is a BIG dose of insulin. No wonder you hypo. Most young men have more muscle mass and better insulin sensitivity so they tend to need lower boluses, unless they are eating great quantities of carbs, or they are very insulin resistant for some reason (usually overweight or inactivity/sedentary lifestyle.
Most people start on 1:10, that is one unit of insulin per 10g of carb. Then you take your bolus fifteen minutes before eating and then test again between one and half and two hours after the bolus. By that point, your blood sugar should, ideally be back in "normal" range (under 7.8), but if it is a lot below that, you may very well hypo again - though not as fast or as badly as you are now.
You might find that even 1:10 is too much. But if I were you I would try it for three or four days, and see how it goes.
The other question, if you are reluctant to go full on and test your basal rate by fasting etc, is what was your blood sugar reading BEFORE bed last night. dId your blood sugar fall much overnight? What you want is for it to stay at roughly the same level.
You don't have to increase your carbs to "feed the insulin". You can cut the insulin to match the carbs. The ideal is to be eating enough to maintain your weight, while taking as little insulin as possible and keeping your bloods in the normal range. If you eat 100g or so at every meal with 10 units of insulin you will pack on the weight ( and possibly STILL hypo).
[So, for example, I am 53 year-old female T1 and my insulin to carb ratio is 1:11 or 1:12. So for 45g of carbs I take only 4 units. It's is extremely unlikely that you need 10 for the same amount of food.]
You can really discount the highs after over-correcting the hypos. What you should focus on is getting rid of the hypos, then you will automatically cause the over-correction highs to disappear. Those hyper corrections may be making your hba1c test high, so your consultant will be telling you to increase your insulin, when by all accounts you may need to decrease it, particularly your boluses.
