I'm 6 days into SP. I've been reading The Spark and using the website. I've been exercising (cardio) every day for at least 10 minutes and have been meeting my daily calorie goal of 1560.
The first few days, I felt GREAT. I felt extremely energized by the exercise, so much so that I had to restrain myself from exercising too much and burning out. I'm typically exercising 40 minutes in twice-daily sessions.
Beginning two nights ago, I started having trouble getting to sleep and sleeping well. I lie in bed wracked with anxiety. Also, I've been feeling extremely sleepy during the day and just generally out-of-sorts -- like maybe I have a cold coming on. But I have no symptoms of illness. I just feel sluggish and completely "out of gas."
Prior to starting SP, I was already eating a pretty healthy diet and exercising regularly, if sporadically. I cook most of my foods from scratch, don't like sodas, and refrain from eating too many sweets. I'm not terribly overweight (20 pounds) and came here mainly to reinforce healthy habits I can use to stay fit for the rest of my life. I'm 51 years old and, no, it's not a hormone problem. Trust me.
Could this extreme tiredness just be a result of my body (and mind) adapting to this new regimen? Could it be the extra exercise I've been getting? Is it possible I'm getting too FEW calories?
Did anyone else go through something similar to what I'm describing? I'd appreciate some reassurance that this will pass. Thanks very much!
