Sorry to hear you had such a rough time yesterday.

I get that from time to time too. It takes me about an hour in the morning to know how my cog stuff is generally going to be for the day. It's a feeling that's hard to describe (gotta love this MS stuff), but the best thing I can come up with is disorientation. If it doesn't go away during my normal wakeup period, it usually sticks with me. Sometimes sensory overload will also cause it to sneak up on me.

My neuro told me to do more stuff to "train the brain". Puzzles, brain games, etc. to try to help it out. Even though I do that, I still have bad days on this rollar coaster ride.

Just thought of something else. Have you started a new med recently? Some of the ones they give us to help with other symptoms can throw our cog issues for a loop for a week or two.

Hope you feel better soon.
