My diabetes consultant prescribed Victoza (exactly the same product as Saxenda, and both made by Novo Nordisk - look it up!). I lost a stone on it but as it was described as a diabetes medication you are not allowed to go over 1.2u I think it was. With Saxenda you can take up to 3u max. I found that as I couldn't increase the dose my body got used to it and it made no effect after a while. I did get Saxenda privately although I'm afraid to say I lied and said I wasn't Diabetic. It just got too expensive to carry on at 3u at £50 per pen (it will cost about £150 pm) so gave up completely with it.
You should speak to your consultant about it. It can make you go hypo so you may need to be cautious and test your sugars more often.
