Very frustrating to have this happen, especially repeatedly.

May I ask how long your typical trips are? The alternator may not be charging it enough during repeated short trips. Personally, aside from weekends, 5-days a week I only drive it 3mi. daily but I've only seen the high battery drain message once but was still able to start the car then. Also, what options do you have, such as ipod, heated seats, etc..
