Hi, welcome back to the forum and welcome to the thread 
One of the things we tend to warn people of is structure fatigue - following an FD plan consistently for 28 weeks is no mean feat, it takes a toll. That doesn’t mean don’t train at all, or don’t train with structure, but it does lend itself to picking a different goal before starting FD.
For example, I’m focussed on swimming right now, and picked LV general build for some structure and variety in the background. My HV HD Plan starts at Christmas.
