I am in need of a significant career guidance/change.  8 years ago I graduated with a degree in Electrical Engineering but I have never used my degree.  I currently work in a project management/inside sales position for a rapid growth manufacturing company.  I am the longest standing PM at the company because of the demanding nature of the position but have come to loathe the job and desperately want a change of scene and pace. 

Essentially I am stuck & would welcome any suggestions as to how I might become unstuck.  Should I have any hope of cracking into the engineering industry?  If so, where should I go to start back down that path?
