I've been using Huel for like 6 months now and I find that twice a day is my max for meal replacements before I start really wanting real food, but I imagine that's different for everyone. Sounds like your max might be 0 meal replacements :/ The one thing I can recommend if you're trying to balance real food and replacement is something like Huel Hot & Savoury, which is almost like a chili instead of just a smoothie. I find it's a pretty decent middle ground for "quick and nutritionally complete but still feels like real food". There are some days that I just have 3 smoothies and 1-2 bowls of Hot & Savoury.
I've actually been trying Huel out! To clarify, when I wrote, "makes me more hungry", that was a poor wording. I meant to say (as you also noted) that after Huel for 2 meals, I find that I am really looking forward to eating actual food (most likely) psychosomatically. In a weird twist of fate, my cousin sent me some hulled hemp seeds, which I've started added to Huel before blending together. This seems to work better! Maybe I'll give the hot and savory a try. Glad it's not just me who feels like eating real food after 2 meals of Huel!
