my gastric bypass RNY experience 7 months out with minor complication but?

My weight before surgery is 415lbs.  I am currently 256lbs.  I can't seem to pass 250lbs.  Although I am still striving to get there.

Now, with my complication.  I have been dehydrated and low on potassium my first two months out from surgery.  After I started feeling some tingling/numbness from waiste on down.  I was low on potassium, and probably B12.  I have seen my surgeon who said it will pass, and sports medicine *****ferred me to neurologist.  Neurologist did some testing and realize that everything was okay expect the response below my knee didn't seem normal.

Now, I can only feel the tingling/numbness below my knee area, but there are times I feel that its getting better.  But if I step on a little pebble...it hurts my feet.  Also, there are times I feel uncoordinated.

My hair is falling out, but its a good thing I have thick hair.  I read some forum that it will eventually pass.  I hope so....I'm getting to be paranoid.

I read about the fish jerkey.  That sounds so good for some source of protein.  I had to drink this nasty protein syrup from the surgeon.  I took it twice and its still sitting on my shelf.  That thing is too nasty but I need to start taking it I guess.

Hope everyone else is doing okay.  Aloha and God bless.
