OP, you sound like you want an easy fix. This really isn't that easy!
You need to stop the fizzy drinks for weight loss, your health and your poor teeth.
It is worth it.
I was BMI of 30 with pre diabetes and started on 30th September. I have remained on 2.5mgs the whole time bar a couple of weeks of 3.75mg, which made me feel unwell, and today I am BMI 25.3. My weight was round my middle and thighs and being short, I looked terrible. My health was terrible too with joint pain, bloating, poor sleep, poor moods, inflammation, blood sugar crashes and no energy.
Yesterday I did my first pilates class in years and I could not believe this slimmer body (I am far from perfect and could do with losing 2 more KG's) was mine! My stomach no longer over hangs and protrudes and my thighs don't rub together. My joint pain and inflammation have gone and more importantly, my pre diabetes is no more.
I felt ropey the first month or so but side effects/withdrawals from sugar soon disappeared and I am fine now. Occasionally get a dull headache the day or two after injecting but that is more likely dehydration as I am not good at drinking and have to keep on top of that.
I sleep great, my moods have improved, I now do pilates and yoga, play tennis with my son, wear nice clothes and can work my 12.5 hour shifts on my feet without any joint pain or inflammation.
So I guess the answer is yes, it is 100% worth it but if you would rather stop and continue your poor habits which are damaging your health then absolutely go back to it and think no more of it.
