Hi Tiara!
Firstly, well done on your weight loss! Like everyone is saying, 8 pounds is way more than 0 pounds!!
As for weighing yourself. I weigh myself every morning roughly at the same time each day. And yes, there are days when you don't lose weight but my secret is my scales. I bought them recently in Argos for c£20. They are scales that weight your fat% and hydration levels as well!! I have noticed that on the days when my weight stays the same, my fat% carries on going down!
I have made a chart for both my weight and fat% that i fill in everyday (line graph) and I watch the curve go down everyday!! TOTAL MOTIVATION!!!
This may not work for you, but it does for me! I guess everyone is different!
Good luck sweetie!
