Question on stretch marks, and water access at home.

Been a Keto lurker since the beginning of February and started on February 9. I am 6ft, 24/m that started at 250lbs (113.3kg) and currently 227lbs (102.9kg). Everything posted here has been great motivation to keep chugging along.

My first question is in regards to stretch marks. I gained marks as I started to gain weight. When I graduated high school all was well. Then getting a job and going to college slowly started to work against me. Went from 185lbs and great shape to ~225 in two years. Then it was a slow climb to 250. During this time, marks have got worse over time. Currently, they are located on the fat between my chest and arms and around my waist. As I keep losing weight (goal is 190) will these marks go away or do I need to add some type of cream along with my progress? Summer is getting closer and I find it embarrassing when I go swimming or have my shirt off and would like for them to go away.

My second question is about water at home. I work a 8-5 M-F job that has filtered water that tastes good. I normally drink 1 liter when I get there, 1 liter for lunch, and 2 liters between 2-5pm. When I get home on afternoons and weekends, I don't have access to the filtered water and live on bottled water. I don't want to keep throwing money at bottled water and adding more plastic into the world. What are some good options so that I can get good tasting water while at home? Brita water bottle, filter, etc?

Thanks again for ketoers posting their progress because it gives me motivation where others keep dogging my diet.
