Try dry brushing also
In addition to working with elimination and water, and the rebounding, you could try dry brushing (especially the problem lymph area). I do both, but I'm bad and am not regular about it. I definitely notice a difference even as quickly as 5 minutes after. Five minutes after I dry brush, I feel a sore and itchy feeling inside my throat like when I've been exposed to airborne irritants. When I dry brush, the last thing I'm brushing are the lymph glands under the jaw line, so I'm not sure if it's the body-wide lymph that gets the throat irritation or if it's an immediate effect from dry dry brushing the lymph glands under the jaw. I'm betting it's them though, because if I only have time for maybe dry brushing the lower body I don't get the throat irritation. For me, the dry brushing is definitely stirring something up.
As a side comment: I see big improvements in my skin health and less water retention and edema throughout my body after I do a dry brushing, which says to me that it's helping my body get rid of some nasty stuff. I also dropped 20 pounds over 3 months just from dry brushing and eating as natural as I can (no real reduction in the amount of food I'd eaten and no additional exercise besides the occasional rebounding). It makes me think a lot of my excess weight is caused by holding on to lymph fluids and other toxins. I'm currently on a plateau on the weight loss, but I also feel like my body is in the middle of trying to deal with ridding itself of a lot of toxic wastes at the moment (been killing off a lot the last two months with colloidal silver and oxygen therapies), and my sleep has been awful recently due to work schedule, which definitely hinders weight loss.
