After a dissapointing xc season, my doctor thinks I may have some symptoms similar to Postural Orthostatic Tachycardia Syndrome while racing. My pr last year was 16:03 and I ran 9:30 for 3200 this past spring but I couldn't break 1630 this year after a harder summer of training than ever before (but not ridiculously harder). I never really felt like myself. My doctor prescribed florinef as he said he's seen it help with similar kids. More on my experiences this season can be found here -

Have any of you ever dealt with POTS symptoms or taken Florinef? Thanks guys.
