Hi Curious:
I had this same problem on a recent job and I talked to my employer and told him that I would come into work a half hour earlier and then stay a half hour later but would need to take an hour off from 11 to noon. This still gets that good mid-day meditation in when Chi is higher. Some days due to meetings I couldn't get the full hour in so I would do a half hour before lunch and then a half hour later in the afternoon.
Once you make up your mind that doing the exercises are a priority you will find a way to get them into your life. Don't be afraid to talk to others about what you are doing. They will support you when they understand how it is helping you. You may eventually get a group of people at work to meditate with you. I know at Learning Strategies they do just that and everyone benefits. It is always more powerful to meditate in a group so try to encourage this if the opportunity knocks.
I found two Tibetians who mediate every Wednesday night and now we have over 40. It isn't SFQ but it is really fun to mix it up and be with them.
