Given how truly awful I still feel 2 days later, I'm really dreading the second one 2 months from now!

Has anyone here gotten them both? Is it true that the second is twice as miserable as the first one?

In a moment of weakness, I made the appointment and actually showed up. I'd delayed getting it for such a long time because of the anticipated day long misery involved. Little did I know it would be so much more for me with a compromised immune system.

Ugh!
