Hi Hart as Northener has already eluded to i have been on both,first I was on byetta which i took too really well, some of the others on the forum that are on it had some nasty side effects which include nausea,but i got nothing ,the trouble with it was that I found initially i lost weight and then after abit it stalled so i mentioned to my dsn that i wanted to try victoza, after abit of a battle and doing alot of homework we both had a meet with my GP and she was eventually persuaded to put me on victoza in april of this year, ive got on really well with it and my weight has continued to go down only bit by bit but it has gone down,the conveinece of the victoza is a good positive point as you choose the time of day you want to take it and thats it then all done.I would say the cost of the victoza is always an issue as its more expensive but if i had to choose betwee the two IMHO it would be the victoza every time, you get started on the low dose of 0.6 then after a week or so you go onto 1.6, i was fie with this to start but then whe i rose to the higher dose i had such terrible nausea so came back down to the low dose and i am now fine.
If you need any help or advice then please feel free to PM me x
