Congratulations @VickyT85! I'm so pleased for you!
I've had similar @JunoRoma - I had the week where I was convinced it was a bug as I had really aggressive diarrhoea, then was fine for two weeks, then two weeks with terrible sulphur burps, nausea, very loud stomach gurgling, some cramps, and some diarrhoea. Back on a non-side effect week now, but can't explain what causes the bad weeks - my diet is pretty consistent. Dose is the same, has happened across two different pens, and I'm also injecting in my thigh.
For me the worst of the symptoms come on in the middle of the night. I managed to cut it off early last time though with a 1am dose of pepto dismal when I first got the burps and churning tummy.
Going to brave 7.5 and see how it goes - I'm finding 5mg a bit of a cursed dose and I've heard some do better once they get off 5. Will report back in due course!
