Hello, I've drastically changed what I eat. For awhile (too long) I've been eating little else aside from candy bars, McDonalds, chips and soda. In a very brief period of time I've developed asthma and sleep apnea. I've changed this; eating fruits and vegetables and other healthy things. I've completely stopped eating any of the junk food I mentioned above. 1st couple of days I felt pretty good aside from a migraine headache or two. 3rd & 4th day I felt really good. Sleeping better and just a better mood. 5th day I felt lethargic. I felt like I really didn't even care if I ate healthier and got healthy in general. The thought of eating junk food put me in a euphoric mood. I'm on my 6th day (which I know isn't long) and I'm getting this feeling of lethargy and a general weakness (I'm consuming enough calories - 2300). Is this normal to go through this feeling of "whatever, don't care". Also, is there anything that I'm leaving out that is giving me this weak feeling? Weak as in perspiring and physically unsteady. Thanks for any help!!
