Tuesday night and Wednesday morning, I had two bad lows. First was a 32, second hit 39. Both without warning and without any telling symptoms beforehand. I treated them and came up fine.

But last night, I started dinner at 108 (I'd been holding steady around there since 4pm despite a carb heavy meal). Within an hour and a half of a full-on Mexican meal, I was 90. I'd even delayed the bolus until about half an hour after finishing since Mexican food usually takes awhile to absorb (something about corn tortillas and high fat).

I didn't want to treat the 90 yet in case the food was going to start hitting. So I went to Wal-Mart with the guy I'm dating...keeping a careful watch over the way I was feeling. Generally, just weak. The effects of too much insulin and not enough glucose.

All of a sudden, I felt horrible. Shakey, liquid muscles, the world was spinning and my heart was racing. I was on the verge of fainting. At 48. He ran to get a Coke, which I tried my hardest to drink quickly while sitting in the middle of the brake fluid aisle.

After awhile of that, I felt better. More restored. So we quickly finished our shopping, he drove home, and I layed down. It couldn't have been more than half an hour later that I was feeling all those symptoms again. Except much worse. Clammy, shakey, literally about to pass out. Yet only 62.

Another quick trip for a Coke and horrible attempts to fit more into my stomach that was already brimming with enchiladas and soda. Half an hour later, 96. An hour after that, 145. Finally, relief to sleep which I woke from at 156.

I'm so frustrated by these lows. First, that I'm not exactly sure why last night happened. Second, that I'm having to consume so many calories and seeing very few results. Third, that they are getting in the way of my life and stopping perfectly fine evenings from continuing the way I want them to. Mostly, I'm frustrated that constant lows are a constant reminder how precarious this disease is.

After the two 30's earlier this week, I'd moved my carb ratio from 1:5 to 1:7. Which is where I was at last night. My Lantus had stayed the same: 26 units in the early afternoon and 15 units at bedtime.

I have two theories as to why last night happened. One: that all the excess insulin from the week before (brought on by insulin resistance) suddenly hit forcing my body to cover every unused drop of insulin. And no amount of glucose could cover it. Two: that the peak from my afternoon Lantus mixed with too much Humalog for my meal and caused a strange turn of events in the blood sugar world.

I've experienced nights like this before in my diabetes history. Long, sleepless nights worried about never coming up, needing a hospital trip, the awful high that would inevitably come (which never actually does). We've never figured out what causes them...and I'm kind of leaning towards theory number one.

It does make the most sense in some twisted world. Considering I'd been on that insulin dose for several days and hadn't seen anywhere near that much "insulin sensitivity."

I've lowered my Lantus to 25 in the afternoon and 14 at night. And my carb ratio is back at 1:10 for now. Hopefully it works. Hopefully there are no more lows. Hopefully diabetes starts cooperating.
