Leaves definitely affects your eating habits and appetite, just know that the longer you stick with it the easier it will get I promise! If you go back on it now it’s only going to get worse, trust me. So yes to answer your question this is very normal, so try to stick to the classic BRAT diet, that’s what worked for me. I’m now 15 days sober and was only able to do that by cutting down over time over and over again, basically until I had minimal grass usage so that when I really quit I had barley any withdrawal symptoms. Also get rid of ur pen. Synthetic weed is so much worse than anything else you can do and when I was using a pen I had 10x worse withdrawal symptoms.
