Does flatline affect your appetite?

Hey guys, I am 40 days in and I am currently experiencing the flatline with zero libido and motivation. I am a bit worried (and trying my best to avoid depression) because I realise I have decrease in appetite. I used to be a skinny foodie. I am those kind of people who eats a lot but can always stay skinny. A year ago when I started my Nofap journey, I feel like I lost the ability to stay skinny at all times. I bumped from 130lb to 170lb within a year. And then I started hitting the gym on a regular basis and get ripped. Too bad my muscle is not very tough though (it's really soft, but the shape is there).

40 days is the longest streak I have since I began Nofap, so this is also the very first time I have experienced the flatline at its fullest. Aside from no motivation and being indifferent at a lot of things, I really don't feel like eating much and I've tried different cuisines to 'spice things up', Mexican food, Chinese food, Thai food, Indian food, you name it. But they all feel very bland and eating feels like a chore. I even tried my favourite dish (Spaghetti Bolognese) at my favourite restaurant and I could only took three bites before getting the bill and leave. It's like the brain is telling me 'I don't wanna' or 'I don't feel like' over and over.

Is this normal? Has anyone experienced similar thing regarding appetite?
