Mazza, I currently take 20mg of omeprazole daily (acid reflux being a known side effect of the sleeve). After my recent arm surgery, where I was prescribed strong ibrupofen and have also been taking one codeine at night, I was told to double my dose of omeprazole to protect the stomach. So ibrupofen is entirely safe, but your stomach is still swollen and inflamed so might be wise to protect it further.
