Just coming up to the three years on the implant. Very quick and relatively painless procedure to insert. The first year and a half I did feel quite flat, had a loss of sex drive and vaginal dryness, however all these side effects did improve somewhat as time went on. I have tried the injection, various combined pills (had to stop due to constant migraines) and the pop pill and this is the only I would recommend. As far as hormonal contraception goes it was mild and mellow for me.
