Blood sugar fluctuations are no joke, particularly for diabetics. They absolutely affect our mood, and can make rational thought difficult, especially if low. Even a small snack can help.

tim is probably right. I'm not diabetic, but I've noticed with my working out, if I don't eat within an hour after expending a lot of effort, I get ... weird. I feel shaky, I am cranky, I feel less capable of dealing with anything outside the norm. So I could easily see this happening to you.

Take care of yourself. And, yes. You are a lucky man.

Your husband is a very wise man and you're right, you are lucky to have him. Diabetes is an insidious disease that wreaks havoc on those that have it and those who are surrounded by it. My former partner has diabetes, so I know whereof I speak on the issue. Those swings in blood sugar can be unanticipated and sometimes make diabetics bat shit crazy. Yes, I said it because it's true. There's nothing like waking up to someone cleaning the house at 2 am and realizing that their sugar is off the charts and they're probably going DKA.  Given that you're not prone to quickly anger, it probably was your sugar. But it could also have come from the fact that you've been in lockdown for so long. Either way, please take care of yourself and remember to eat regularly because low blood sugar is a lot more serious that just being "hangry" for you.  I know that tim has the "eat sensibly" part covered. 

Thanks for sharing this with us.

Sometimes things are learned the hard way, we're not always wise to the simple things.

I know from when I've had arguments with my husband. 

At least you and tim were able to talk about it and solve the problem that caused your anger.

i learned what it possibly could be from Wayne. But it made sense. Normally, You never react that way to me being hurt. i was too upset to think about rational things. i'm glad i spoke to Wayne who offered the suggestion.

Life throws us daily challenges. Yes, you and tim are very lucky. So many couples lack the solid communication skills you've developed and fostered in your relationship. 

So many physiological things can affect our moods, it's impossible to recognize them all. Now you know what to watch out for. 

Thankfully you're both okay. 

i am so glad You and tim are ok
being able to talk to and really hear a partner after emotions are more in check is key, i think
i can relate to the apparent overreaction, Phil can get snarly when His blood sugar tanks, it happens much less often now that He has a continuous glucose monitor, but it does still happen

I'm glad things settled for you guys. I feel your pain. I am hyperglycemic, and it's the cause of most of the spats between me and my husband. I know you're not asking for help or advice here, but the mother hen in me wants to point out a couple tips that will help you or anyone that ends up with their sugars dropping. Always have orange juice or simple syrup on hand, those two are the healthiest way to get your sugars to spike. Sugar water lasts a long time with out expiring, we keep a soda bottle of it in our fridge. Another thing is making sure you are eating enough carbs and protiens, that's the reasons snickers bars work so well when people are "hangry", they have quick sugars, carbs, and proteins. The last thing eating on time, set an alarm if ya have too, but make sure you eat something every 3-4 hours, it doesn't have to be a meal. Just a hand full of nuts, or a few slices of apples. Random sugar drops can happen to anyone, whether you have a condition or not. I am sorry for the long and unsolicited response, but living with sugar problems for 30 years now I figured a couple tips would be beneficial to you and anyone who reads this.
