oh you poor thing!! I know how you feel as I am 4 days post op and yesterday was my worst day. I had the same "what have I done" thoughts, but after sleeping well last night (after taking some pain med) woke up a different person. If you feel concerned though, ring your doctor, you alone know your body and how much you can stand.
I also felt feverish and could only sip, but today feel like a million dollars, I have done house work and looked after the kids but have sit down every now and then.
The other thing that makes me feel great is that I am 5.5kg lighter (10lb) and feel so different already. I have used a lot of alternative remedies too(I am a bit of a hippy chick).
Arnica cream around the incisions(not on the wounds) and the spray under my tongue which all helps with bruising and and inflammation and also a powder probiotic in my Water to get the good bacteria back into my stomach to help with the acidity. Also "rescue remedy" which is a flower essence to help the shock of surgery and some liquid zeolite which gets all of the anasthetic and drugs out of your system quickly. It is just a help, I think to give the body a helping hand. I know this sounds a little out there as well, but I have been doing some visualizations (of me slim and trim) and it makes me not want to give up.
Hugs to you and I hope you start to feel better:heart:
