Study for school after work out

I have a problem focusing on study after exercise. While I am sitting at desk, my legs ache that interferes my focus. My legs are so restless that I need to have a break. I often walk around the room or lie down on bed a while. Then I lose time for study! I remember now this was the one of reasons I quit my exercise when I went back to school in spring. I am not morning person, so doing exercise in the morning is not my option. Does anybody have suggestion how to reduce the restlessness of my legs, especially after exercise?

How is your potassium?

I've never really paid attention on potassium, but I don't think I have it too less. I eat green leafy vegs, banana, and chocolate(!).
Maybe I should drink more water...? I'll see. If drinking more water solves my problem, I will update here. Thanks!

Well, maybe the soap trick that works on leg cramps would work on restless legs, you could try it.
For the leg cramp issue, Dr. Peter Gott - a retired physician whohas a syndicated newspaper health
advice column, recommended rubbing a new, dry bar of most any soap except Dove brand on your legs. Also, keep a bar of such soap under the bottom sheet in your bed. Worked for me. Look for his column
in your local newspaper.

Add a small glass of OJ into your diet, the idea of the potassium is right on the money. Also, try to get some quinine into your diet. It's found in tonic water. So try a fruit spritzer, or get some low cal gin and "cheers"! You might be able to find quinine in pill form in the herbal/natural/organic section, but I think that's a much larger dose that isn't necessarily needed. Good luck!

I had been doing alright since I posted here last time, so I almost forgot this. Recently, I adjusted my exercise form for lunge, dip, and squat to make it deeper. Then BAM! The restlessness came back. So, it seems that what I felt as "restlessness on my legs" is a form of muscle aches. I'm doing workout DVD, so it usually includes some stretch at the end. I also do pilates, often after workout DVD. Maybe my stretch is not enough to relax my legs. I don't know. I am going to add more repetitions for leg stretch and do massage after workout. I'll see how it works. Oh, and of course, I try drink more WATER!
Thanks everyone!

I am glad I read all these, since I was going to suggest that you make sure you stretch out well after you work out! See you figured it out pretty much on your own, lol. Yes, drink more water!
