I have put on 5.6 lbs in the last week and a half.. im so sad about it

... I had three big infections going on at once- mastitis, sinusitis, and an abcessed tooth. The dr put me on some strong antibiotics as well as some other medications that made me nauseated but in a weird way. If my stomach was empty i felt like i was going to heave, and i craved carbs.. french fries have been my main food for the last week and a half..the one day i didnt eat any fries ( or anything else cause the thought of other foods was yucky ) i threw up 3 times..so, today is my last day on my meds, and i need to really get back on track... i did feel well enough to get on my excersize bike for about 10 mins today(doesnt sound like much, but is way more than i have done this past week ), and i managed to get down some special k (no fries - so far so good).
I'm hoping some of the weight is water as my ankles are swollen this am really bad... fries need loads of salt

... i guess im mainly just venting and re-affirming my goals... thanks for listening...
hope things are going well with all of you this am
