Help Terrible Feeling Options

So i just tried to astral project i was laying down on my bed. I was clear and focused for about 30 minutes. After i finished i felt really sick and weak it is hard for me to even type as im shaking bad. I feel almost out of place. Feeling like i was going to pass out like im drained it feels like i havent eaten in weeks. Can anyone offer advice on this this is first time anything like this has happened. I didnt project i just felt really relaxed until i came out of it all these things hit me at once. Any help is greatly appreciated.

The first thing to point out is that only you really know what was responsible? Was a spirit ally having fun with you because you had been slacking? Did your body revolt from eating?
Was your protection shoddy? I could probably list 25 things off the top of my head that could have been a problem in your situation, the thing to do, is carefully review the event and the events before and after and see if you can figure it out.

I did want to point out that, in my mind there's no such thing as too much relaxation. If anything I would say the problem was that you weren't able to relax enough. After all a relaxed body and mind don't often get upset stomachs and its actually pretty hard to feel 'terrible' when one is really relaxed.
