Some meds do contribute to water retention ie. Tylenol and some other pain meds. But that is minimal and easily counteracted with increased fluids... which you should be doing when you have an infection anyway. Overall though if you tell the staff at your centre about what you are one they would know best as far as what might affect your scale numbers.
Also, if you are lagging in energy you can try a multivitamin. Your centre will sell one but you can find one that you like at any grocery or drug store. Also, you can try picking more nutrient rich foods such as sliced almonds as your fat exchange. Any fruit or veggie that is a more vibrant color ie. butternut squash, yams/sweet potatoes, carrots, tomatoes, peaches, berries, etc... as opposed to salads (apart from spinach which is very good for you), apples and bananas. Be adventuresome! There are some delicious foods out there that are super for our bodies and taste good too!
I am overly verbose today ... sorry LOL
