After returning from a trip I've been pretty sick. As now most of my family has it I think it is a virus. What I'm really concerned about is my diet (Most of the food I eat gose straight up again) and the Gym (I'm feeling too dizzy to go to workout)

I am planning to go to the doctor if I don't get better today, and I'm already taking Ibuprofen to relief the pain (not workong very well) and something for the stomachache.

Any tips to remain in shape and mediumly healthy while being sick? and any good advice on how to mitigate the symptoms in order to carry on my lifestyle?

PD: My symptoms include dizziness, headache and stomachache and common cold symptoms such as cough and nasal congestion

Thanks in advanced
