So sorry to hear you are feeling so bad at the moment, constant coughing is extremely draining. Sounds like a plan with the vitamins, it maybe that you are a bit low on some.I was suffering with hip and knee pain, compounded by actually injuring one knee. The recovery from that was so slow and I know my weight made it worse.
Hang in there, it's not too long now. The first date I agreed with Frederik was 17/3 but that couldn't go ahead so date was put back 2 weeks, making a 6 week wait. It seemed ages (with apologies to NHS patients who wait so much longer) but trust me it flew by.
