I am glad to know I am not the only one with this problem. I use the acacia supplement and drink fennel tea, but I still get that pregnant look too. I too have resorted to pants with waistbands to allow for a growing tummy thruoghout the day..My tummy slowly gets larger thru the day till I am miserable with a tight belly at bedtime. I start off the day fine.. I just don't understand!
