I started a 5x5 routine about 4-5 weeks ago. I had no one to teach me the lifts so when I started I had horrible form on everything, so I could only do minimum weight and because of that I was unable to find my proper 5 rep max. Due to this my routine was pretty half assed, I would just jump up weight when it felt right versus actually following the numbers as they are set in the routine. Starting last week I finally found my grove with both weight and form which allowed me to jump up 15-20 pounds from the previous week in most exercises. The problem I am finding now is that once I started going heavier I began to have difficultly sleeping. This started last Wednesday and the only day I was able to sleep fine was Sunday night(2 days after my last lifting session). Today I decided to check the web to see if they could be related and found that insomnia is a symptom of overtraining, along with increased chance of sickness(cold/sore throat), longer recovery time, and decreased appetite; all of which I have. My question to you all is, do you believe this is a case of overtraining and if so, what steps should I take to correct this? I know rest is a major factor, but for how long and should I do some mild lifting or cardio? And if you don't believe this is a case of overtraining, any thoughts on how to help me sleep other than alcohol or pills? And before anyone mentions it, sex doesn't help me fall asleep any easier either.
