I've stopped my fluid intake due to frequent urination,for a couple of days&I've lost many inches&pounds.Why?

I'm 32&have suffered from chronic UTI's&overactive bladder since the age 0f 15.Once I'm off antibiotics it comes right back.One day I just tired of my daily 10 trips to the bathroom,I decided to stop my fuid intake altogether 3 days ago.Remarkably after just 1 day,I actually was able to see my waistline again&fit into all my old pants&was finally able to sleep face down with no irritability on my bladder.Now on my 3rd day,I've already lost so many inches�s.What I haven't been able to do in such a long time.I'm a lot tired,of course&weeker&continue small fluid intake in my foods.Why am I experiencing the opposite effect of what everyone has always been advising me?Drink plenty of water and your UTI will be flushed away and you'll lose a lot of weight.I think with me more fluid in my body made me more prone to urinary storage causing infections and I was retaining all the fluid in my body.Has anyone experienced this?
