Did the same thing about 2 months ago. Double red is a much different experience than a regular whole blood donation. On the upside, you don't have to give as often.
I give whole blood regularly and was asked to give double red due to a shortage/need for A+. I had no idea what it would do for my recovery.
I'm sure everyone's different, but it took me a week+ to get back to "feeling normal". Every time I went in to WOD, I felt fine initially, but not even half way in, weights felt heavier and I was tired (not necessarily winded). Also didn't get that nice little endorphine kick/energy boost I'm used to post-workout. It felt exactly like I remember when I left KY in college to work out in Buena Vista, CO (200 ft to 8,000 ft in elevation). Would make sense as both account for fewer red blood cells than needed to be efficient.
Just realize your body is working to recover the lost blood cells. It isn't you and you'll be back to normal in a week or two.
And good on ya for donating!!!
