i work w/ my cde w/ regard to gaining weight, but little is working. i might be able to gain a pound only to lose it again the next week. i eat high fat food 'round the clock w/ little or no success. recently i have tried doing dual boluses to include more carbs. i'll see how that goes. i have, as you picked up on, little sub q body "fat" which has lead me to insert my sensors to my upper outer thigh area. i have found great success w/ this location. Phew. i have also overcome the pump site problems using my outer hip area. so basically, almost all is well.
