Feeling fuller quicker

Hi all. Just a query,

Was sleeved on 17th December, almost 3 months now. Recently like in the past week it feels like I’ve taken a step back in that I cant eat as much as I have been for the last 6 weeks. Like I’m getting full off of a smaller amount than before. I’m worried I’m not consuming enough as I’ve been feeling crap for the last few days too. Is this normal to have? Anyone else experienced it, could it be something that just passes?

I have been doing well I think in the last 12 weeks. My SW was 298, CW is 238. So down 60lb since having it.
