Anadrol questions/water retention

[john3:16]

I'm getting ready to run my second cylce soon. 12 weeks of 500mg per week of test e, 250mg per week of deca (mostly for joint relief) and anadrol 50 at 50mg per day for 4 weeks.
im running arimidex on cycle and will do PCT with clomid and nolvadex as prescribed on this site. im 37 yrs old been training for 2 years (this time) 6.1 tall and weigh 220 and don't carry much fat, although I don't know what percentage at this time.

When should I be taking the Anadrol? morning, evening or pre-workout?

I have read that water retention could be an issue if not controlled. My question is what are the best ways to control water retention. I drink at least 1 gallon of water a day. Are there any other ways to help with retention. My diet consist mostly of protein shakes/creatine/fish oil... lean red meat, including deer and elk, salmon, yams and broccoli...

Thanks for the knowledge
