Nicotine Withdrawal Symptoms

Since I'm currently experiencing several of these, let me list the mental and physical symptoms I've experienced when quitting nicotine:

• Irritability
• Oversensitive hearing and skin
• Inability to concentrate
• Nervousness
• Depression
• Muscle tension

Sounds milder than the side-effects of some of the more heavily advertised anti-depressants.

Also, the nicotine seemed to hinder my RLS (Restless Leg Syndrome). It's coming back, but hasn't gotten too sever yet (severe for me is having to get out of bed and walk around for several minutes).
