Nyquil got to my diabetes

I have been battling a cold and cough that is really getting to me. The pains in the back are finally gone and today I was able to get back on the treadmill.
I had an interesting experience a couple of days ago. To finally be able to sleep, I decided to take Nyquil to get a good sleep. My after dinner sugar number was 151. I took Nyquil later in the night before I went to sleep. Did not eat anything before that. Woke up in the morning and checked my sugars, I was at 157. It was shocking. My morning fasting sugars tend to be in the 120's, not good, but atleast I can predict them. This was totally out of the blue and threw me into a really bad day of high sugars.
Now what really happened. I kept thinking about this. I realized it must have been the Nyquil. It has alcohol in it and all is very sweet. The sugars must have gotten to me. I was amazed at my ignorance. I never thought about checking the contents of the medication. I keep looking at all the foods that I eat, but the medication I forgot about.
Everyday is a new lesson to learn. I learn now that I need to think and evaluate anything I put into me for sugars. I see a bunch of diabetic friendly cough and cold medication that I could and should have taken. But atleast I learnt my lesson and will be careful going forward.
