So how long did the fatigue last? How are you feeling now?
I know exactly what you are talking about. The fatigue is the part I hate the most. We are in such a hurry to feel better, and it seems to drag on forever. Keep this in mind....five days is huge. You should be very proud. But at the same time, you are so early into this. When looking at the big picture, 5 days is nothing. You will feel more and more normal from this day on, but it's going to take time. I woudln't say that the fatigue will last months, but in my personal experiences, it is the last thing to come back. Don't let this discourage you....within a few days, you will notice a big change in your energy. Remember to eat right, drink plenty of water, and EXERCISE. It really does help.
Hang in there...you have done an awesome job so far. Put on some nice motivational, touching music, and sit and think about why you wanted to quit. Think about where you want to be in a week, or a month, or a year. You quit for a reason...never ever forget those reasons.
Take care and God bless.
