It's pretty challenging in the beginning and at less than two weeks out what you're going through could be considered normal. Are you taking medication or supplements (besides the Vicodin)? Is your doctor okay with you taking imodium, lomotil or fiber supplements?
Is your pain constant? Is it just when you eat? Do you have problems with evacuation (other than the number of times per day)?
Start keeping a food diary so you can ascertain if certain foods are problematic right now. If they are, eliminate them from your diet and reintroduce them again later. Some problem foods are dairy, eggs, sugar, tomato products, wheat products, caffeine, sodas, fruits/fruit juices/smoothies. Even some of the recommended foods don't work for all of us. Peanut butter and applesauce don't have the desired effect on me. I know it's all trial and error but it's the only way you'll figure out what works best for you.
Try to measure advancement weekly or monthly rather than daily. It's often very difficult to tell if you're feeling better than yesterday.
But.... if you think there's something wrong then go with your feelings and give your surgeon a call. If he says all is good at least you won't have to dwell on the 'what if's' for a while.
