Clearly - yeah, I don't remember doing any not all out except for a few of the most recent. I don't think I'm iron deficient, but obviously I don't know. What foods contain iron? I just don't want to waste the doctor's time on something so trivial compared to what they should be doing.
as for overtraining, I initially thought it was the cause, but my reduction in training slowed me down, and hence I may instead increase my load.
thank you both for taking the time to write such informative replies.
