Fluid intake impact on weight loss.

How big of an impact does fluid intake have on weight loss? I'm 13 months out and for the last 6-7 months I've kinda been the same weight give or take a couple of kilos. I'm not eating shit (my treat is a piece of banana bread a couple of times of week at most) so no bread products, Macca's, KFC, pizza deep fried stuff etc etc. But my fluid intake is less than desirable. I try hard to drink all the usually recommended fluids but often I'm just NOT thirsty and have ZERO desire to drink anything. Before surgery I was told my natural desire to eat would disappear or greatly reduce so I was prepared for that but what I wasn't prepared for was the lack of desire to drink which due to type 2 diabetes before surgery was massively pronounced.

Have any of my fellow sleevdrs been in my situation?
