Hello Vicaversa, to answer better this question I'd like to know more about your experience, if it's possible. I'll try to help in the best way I can.
Yes, it will lower your vibrational frequency, which will either hinder you from projecting or if you still manage to project you'll be vulnerable to attacks and might see some unpleasant/scary things.
Ideally you shouldn't smoke and drink in the long run as well , but if it's too difficult for you try to make it occasional.
Also, if you're going to project, I recommend to not smoke and drink for at least 3 days prior the attempt.That will give you sometime to raise your vibrations.
Well I'll be damned! I know what you're talking about.
I hate swallowing reflex, used to have all the time, but now decreased. I also get jerking a lot. I don't really know how to stop it though.
But if I were you I'd not give it much thought, it's something we'll never know when it will happen, furthermore, it's a good sign that your body is getting ready for projection.
My only advice would be: try to keep your position once this happens, like it was no big deal and just continue with your projection.
It's just your body testing you.
