So I'm about to be finishing my 2nd week of insanity. Im feeling a little off. Not during the work out but before it. Today I'm off and I been feeling off pretty much all day. My throats really dry no matter how much water I drink, I feel like my eyes are a little hard to focus sometimes, my hearts racing too. But when I work out I'm fine I don't understand it. I also suffer from anxiety I heard,that losing weight can cause it, I've also stopped,smoking cigarettes cold turkey and stopped drinking caffine. Could it be withdrawals from that? I also take the medications methotraxate, enbrel and benedryl for allergies.
