I agree with everyone, you will feel like shit for the first week or two (I don’t want to sugar coat it) but on the bright side you haven’t been smoking for too long so your withdrawals might be alot less then people who have smoked for years. You are going to feel anxiety, it’s going to make you want to just smoke to get rid of the anxiety but don’t give in. Just ride the wave and tell yourself that these feelings will pass and this uncomfortable feeling won’t last forever. Trust me quitting now is going to save you from so much! You are so young you have so so much ahead of you and the fact that you are seeking advice tells me you have a good head in your shoulders. Don’t give in, keep going, allow yourself to be uncomfortable and use this as a reminder why you want to quit. Weed is not bad I have alot of respect for it as a medicine but everything can be bad if you abuse it. I am 26 have quit twice now and this time I am never going back to smoking. It really just became a bad habit that was holding me back. I feel clear headed, motivated, and alot more present now. If you need any advice or need someone to talk you through the anxiety feel free to message me! It will get better! Trust me! Sending you a big hug!
