my wife really only started smoking after she got her card, in her 40's. She would join me once or twice a year before that.

I noticed her go through the stages of being a beginning smoker, getting higher, getting uncomfortable/spins if she used mj and alcohol at the same time, paranoia, etc.

After a few weeks of daily use, it got more normal for her, and the unpleasant side effects went away.

I would just suggest taking it easy and having a little daily for awhile while you get used to it. If you want to try a higher dose, just do it before bed then getting tired wont be a big deal...
