Could hypo 'fog' be like little blackouts?

[Leval]

I'm kind of hypo and having the predictable symptoms, but I'm wondering if there's something else going on, too.  Though I'm foggy in lots of ways, sometimes I seem to be blanking out (if not blacking out).  It's like somebody hit the Fast Forward button on my life and I'm in a new location not knowing how I got there or what I've been doing.

Nothing exciting yet like, Wow! I'm in Vegas! And the croupier is shoving stacks of chips at me!  

Just stuff like it's night and I'm standing in the hallway of my apartment building, barefoot, holding keys.  I don't know why.  I remember being in the kitchen.  Maybe I took the trash to the trash chute.  Nice that I took the keys with me.

Or I'm sitting at a table at the deli with my lunch sandwich, realize I'm holding a $10 bill and can't have paid for the sandwich and so go back to the register that I must have simply walked past unnoticed.  I remember going into the deli, but not getting the sandwich.  It is the sandwich I usually get there and the counter staff aren't looking at me like I've been acting weird, so I'm guessing I was acting okay.

I had a TT on 7/18 (papillary thyroid cancer) and am on Cytomel, 25 mcg twice a day, pending a decision about whether I'm going to be given RAI. I do better on 25 mcg three times a day, but my endo is seriously nervous about that third pill, so I haven't been taking it at her request.  The only other med I'm on is my long-established 10 mg a day of enalapril for high blood pressure.  

Worked four 10-hour days in a row this week, seemingly okay work performance wise, but am now half dead.  No slurred speech and no weakness on one side of my body or anything stroke-ish other than these... surprises... once or twice a day. Have decided not to drive 'til I'm sure that whatever this is has stopped.

Thanks for reading this.  If you've had a similar experience or know what I should search under for answers, I'd appreciate your thoughts.

The last tests were last week.  Endo called to say they were "near" normal and given what was going on at my end at the time, I didn't ask for details.  Will be tested again next week.

Usual range for Cytomel given online is 25-75 mcg/day so I'm right in the middle of that.  DId better on 75 than 50, but the endo was uncomfortable with 75 (a few days after Rxing it) and asked me to cut the midday dose, which I have.

BP med's insert lists no similar side effect -- and I've been on it without probs since 2004.  

But thanks for the thoughts.  I'm at a loss.  Will see what next week's endo has to say about it as well as about RAI.

When did you have your last thyroid tests done and what are they with ranges.
Also, read what the side effects of your blood pressure medicine are....that might be the culprit. If you can't find the sheet that comes with your medicine from pharmacy, go online and get a full description of side effects possible.
I agree with AR- that is an aweful extremely high amount of cytomel.

On Cytomel alone pending a decision on whether I need to have RAI or not.  Apparently Synthoid's too long-lasting to precede RAI.

That is not Brain Fog as we know it.

That must be very unnerving. I don't have a clue what might be the cause.

Why are you taking only Cytomel? That seems a bit out of the ordinary.
