sweet- i basically waited to eat when i knew what i was going to eat, and it really helped. only once over shabbos was i over 200
reb- sorry to hear. hopefully you wont have to wait too much longer
allgr8- i personally like the medtronic, but i keep it in a pocket which is easy access. i did keep the pump in a pocket for my daughter and cut a hole from the inside for the tubing to go through. someone once mentioned to my wife about sewing a pocket on the inside of clothing.
there is something called a pump band that i saw on pumpwear.com which is meant to cover the omni so it wont be so noticable.
whatever you choose will be great. Once you adjust to it you will love it!! :):)
