I need help with recovery from illness

Recovering from double pneumonia and septicaemia, liver function is impaired. I understand detoxing might be stressful on an already stressed liver but so is being tired and feeling unwell. Work full time and voluntary work, am trying to decrease latter. practise a little qigong and not much else, Doctor has advised not to have increase heart rate too high until further recovered. Eating mostly carefully but notice weight gain and cravings owing to exhaustion. would appreciate best way to heal liver. I take daily multi minerals, vit C beta glucan, milk thistle, dandelion complex, magnesium, vit D and carrot, beet, celery, ginger. Eat spinach as much as possible. Am Kapha disposition in ayurvedic system so need to keep heating foods. currently living with others during recovery, diet is quite different to my normal which does not help.
