I think I had my first experience of proper flu recently.
About two weeks ago my chest started to suddenly feel a little tight and wheezy and by the next day I was extremely unwell.
For the rest of that week I was in bed, I slept all day and all night, just going to the toilet made me feel extremely sick and drained whatever energy I had, I kept getting chills and a fever which I couldn't shake, lots of horrid phlegm being coughed up, no eating for days etc...
I have never experienced muscle tiredness like it my whole body felt like lead, even my eye lids hurt which sounds dramatic now but really! I felt like I could barely even reply to DH when he would ask me a question. Basically... it was shit!
But anyway, it's now about 2 weeks down the line and I am much better but I still don't feel 100%. Being at work just zonks me out still after 20 minutes and I feel like collapsing into bed, I'm still quite achey and sore and my head feels like it's got an elastic band around it. Food wise I can eat but not nearly enough, I'll randomly fancy something like a slice of pizza at 7am but then want nothing else all day kind of thing?!
I'm definitely better than when I was in the throes of whatever it was but I'm not better yet. When will it happen?! If you had flu badly when did you feel like you again? I miss things like going to the gym and I just can't face it still.
