So I have been cutting since Jan 1st and everything was going very smooth untill last week. All of a sudden I got a ton of strange symptoms all at once. Intense chills/cold all the time, insomnia, VERY intense and irrational anxiety/depression,crazy fatigue. . .Pretty much just going from feeling normal to the worst ive felt in my life in a matter of a few days. I literally felt like a different person. After 2 days of that I bumped my calories up by a ton and have been eating well over maintenance for the last week. Feel great and back to normal so I want to get back to cutting this last % or two. But something tells me this incident was diet related. A few things that concern me though are- 1) I have not been taking a "hardcore" approach by any means. My cals have never gone below 2500 in a day. Most days they are closer to 3000. I have not been cheating at all just keeping cals at arround 2500-3000 a day for the last few months. 2) I'm not lean. I would personally guess I am about 12%, but there is no way I am 10% or below. 3) This came out of nowhere. I literally went from feeling normal to trainwreck in a matter of days. So just wondering if anybody has had the same/similar experiences? I want to continue and actually try to hit single digit BF so I just want to get things completely dialed in . .
