I found Slissie very easy to use and the instructions easy to follow. It took approximately 1 hour to charge it and lasts me atleast a couple of days. It is charged by a USB cable so can just be plugged in to your laptop whilst at work. Slissie doesn't give off any smoke or produce a strong smell which means it doesn't affect people around you and is rather discreet. This means you can use it anywhere without it being a problem. The flavour isn't too strong but really tastes nice. I particularly loved the mint one as it gave me lovely fresh breath and also tasted great.
After 2 weeks of using Slissie I have definitely seen a huge decrease in the amount of snacking I have been doing. I don't know if it is the habit of having something in my hand and in my mouth when feeling the need to snack or the actual flavours of the Slissie but I do know it definitely helped! Although I still have 2 weeks left of my challenge I feel this is really helping me and can see me using Slissie a lot in the future. I just wish I had it from the beginning of my 28 day challenge as I just wasn't doing great. I will be doing the 28 day challenge again properly in January so will be using this alongside the challenge to hopefully produce some great results that I can share!
