Ladies I have a question

I am trying to loss some weight and trying to stop drinking pop. I think I am addicted to Mountain Dew. I don't like the diet one how it tastes. Is there other people who loved pop and stopped drinking it. I know I will loss weight if I stop it but I get headache if I don't drink it. I only drink it once a day because I feel like it gives me energy since I am not a coffee drinker. Ladies give me some tips to stop drinking pop.
