Radiation - with or without tattoo

Thanks @Zoffiel and @Keeping_positive1 . That is good to know and a really positive way to look at it :). Any tips to share on what to do during rads? 
- I have been advised to apply strata xrt and moogoo cream. How often did you re apply in a day? 
- Is it ok to still take warm showers ? Did you bathe in salt water on weekends? 
- any change in dietary requirements?
- any exercises you would recommend ? 

Thanks ladies. 😊
