I was on the implant for 9 years since I was 16 & decided to have a break from it in the hopes that my weight, libido & mood would change. Turns out without it if still fat & depressed with no sex drive
Honestly though I think it's good to take a break for 6-12 months just to see what your body is like especially if you've been on it from such a young age. If you're not sexually active right now & don't feel like you will be for a while what harm can it do?
Since I feel no different I might go back to the implant although i'm tempted to go for the coil/IUD but i'm terrified of bad side effects!
You can get pill from the GP/pharmacist to stop your period if it starts whilst you're on holiday.
