I can tell you from experience that seeing that many providers do have its pros and cons. It does feel good as fuck though to fuck that many providers in one month. However, it cost a lot of money 
The physical impact is, it can be very exhausting. I spend hours searching for providers and reading their reviews. Sometimes, I see providers early and late in the hours, and that can effect my sleep cycles. As with diet, shit, I need to eat a lot of healthy and appropriate food, otherwise I wouldn't be able to make it. Sometimes, it is harder to cum seeing so many different providers. The overall physical body just feel very tired.
The mental impact is, you always have to be mentally prepared. Gotta have a plan B. Sometimes, I go with plan A, then plan B, then plan C all in one day. Let me speak from experience, it is not that enjoyable anymore fucking to see that many providers in a day. Also, it is not mentally satisfying to fuck that many providers in one month.
When you fuck that much in one month, you tend to become a free goose. I wasn't mentally sound, and my behaviors were somewhat erratic because I was fucking so many providers and losing my sense of reality.
It does feel good though, if you have the time and finance for it. It also feels good if you have nothing to do and are not busy. However, if you have to manage everything in between such as a job and other relationships, it can be extremely exhausting. When I fuck that much in one month, I become very careless.
I try to keep it to 4 or 5 a month on a regular for a healthy habit, maybe even push it back to 3 or 4 a month sometimes. I feel more hungry for it than overindulging. Sometimes, my eyes are too big for my stomach, and that has happened several times.
