Thanks for writing, JC.
Yes, this is common. i see this all the time. The other day, I saw a woman who was having dizziness on alternate days; so when symptoms like that turn on and turn off, just like yours did, that is clear evidence that it's MBS!!
You don't need to worry about it. This is all MBS. You just need to focus less on these symptoms; put them into the background; gradually make yourself less worried and concerned.
They will eventually go away!!
