Is the cold already gone?
Try this: load yourself with vitamins for one days. Use some glutamin if you have one. Spread vitamins and glutamin (even whey is a good source of glutamin) into almost every one of your 6 meals you have over the day (I assume you have). In the evening get yourself a pizza and eat it just before going to bed. Put two pyjamas on or a hot sweater over one and you should wake up feeling much better. Trust me, it works great for me.
I’m reading your journal constantly. Just keep it up.
