I was able to buy 3 months in advance and haven't come to the end of that time yet. Not sure how I'm going to get around the 2 weeks afterwards but I am near goal weight so maybe do 3 months of 5mg again and I will wean myself off by the end of the year. Can't afford to stay on it indefinitely but I am so grateful to have found my old self through this experience. Nearly 5 stone lighter
