Ok this has been happening now for over a month. I thought it was due to my cannabis usage, but I've stopped for the last few days and it hasn't helped at all. It seems whenever I wake up I feel almost slightly hungover in my stomach, like a type of lingering sick feeling but it only stays for about an hour after waking up. It's weird.

I thought it could have been the cannabis because I thought I was getting dehydrated or something. By the way, in the last 6 months my diet has really gone to shít. It's only in the last month that I've been trying to regain regular eating patterns.

any ideas?

You could still be getting dehydrated. You probably are. Drink more water.

Could be stress, nerves, anxiety or a combination.

Cannibus does have an affect on the nervous system as far as I know, and can cause anxiety for a long azz time even after use. I just have to have a look at many of my friends and brothers friends to tell you that..............

You're probably pregnant.
