I wish I could vape at my cube. My company is extremely secure and red-tapish. Everything needs access, everything is micromanaged at some point. To smoke a cig it takes you 5 minutes to walk through the building, pass through security gates, walk about 5-700 feet in the back lot where you can smoke.
I used to take my e cig out with me and people gave me strange looks, those that smoked would just say as long as its helping it can't be bad, they were wondering how it is. But now to avoid going out there, I just vape before I get in my car to go to work, then on my way there when I am about 20 minutes from the office. I take long enough drags that keeps me off edge. After a few days, I don't go out for a vape after lunch, I can hold on until I get done work and back in my car where I can vape on my way back home. It sucks but oh well, better than getting canned and then figuring out how these school loans/bills are gonna be paid.
