Thanks, everyone for the support and confirming what I already suspected.

I've been taking iron supplements every day for two months now, and b12 tablets for maybe two weeks. I was feeling fine for most of the past two months, but suddenly last weekend, I just lost all energy and haven't seemed to regain it. Hills that I used to ski up with no problem are now so difficult that I have to rest halfway up.

There has been a little flare up of UC, so I'm sure that's not helping.

The only reason it's bumming me out so much is that I have the Birkie next Sat. and my doctor appt. is the week after.

Well, maybe the good that will come of this is that I can address the problem soon and get it under control in time for a good cycling season!

I appreciate the responses.

Kate
