Tired today but managed some cross training in the evening

I was very lethargic most of the day. I ended up gathering enough energy to hit the health club in the evening. I ended up doing some light weights, 20 minute bike, 30 minute swim. I am feeling a little soreness in my left achilles so I am taking it easy today. I usually can fix any sore tendon with the following. Light massage, ultra sound, DMSO, alleve, hot/cold treatement, foam roller, light stretching, and a bunch of antioxidant supplements and anit-inflammation foods. What used to take me out for weeks now only lasts less than 24 hours.
