I started biking to work last summer and after a few weeks my sweat levels went way down to the point where I'd just change shirts and put on a bit more deodorant when I got to work and it was fine. If you wear shirts that breathe a bit and use a pannier instead of a messenger bag it's not so bad. I use REI hiking shirts and leave the top two buttons undone to keep the air moving. Coming home can be a bit worse because it could be >90 degrees but in the cool morning it's fine. Fortunately we do have showers though. Some of my coworkers have 20+ mile bike rides into work and they really need them. Mine's only 3.5 miles.
