Dear Beautiful,

First of all, i think you choose your environment VERY well... If i had a bathtub, im sure i would reach the nirvana while smoking... :jointsmile:
You did well smoking slowly too. This way you could control better the level of the high.

Anyway, i think you didnt smoked enough to reach a real high. It seems you felt just a bit of the effects. The vertigo is one of most notable effects of the indica high. When youre HIGH from indica, you lay down and feels like youre moving (or spinning) at a great speed... you can almost feel the wind on your face... it is nothing more than an extreme vertigo... for me (and im sure for a lot of stoners) its a very pleasant feeling...

Woozyness and dizziness are "classical" effects of indicas too... when people say indica gives a "couchlock" high, is because sometimes you just have not another option else stay locked to the couch, feeling your body is somewhat melted, completly dizzy, with the mind sloooow, somewhat confused, but also happy and peaceful...

The anxiety you felt can be probably an mental reaction, like a "trauma" from your first (and unpleasant) experience. Maybe you started to feel some effects, then remembered of the first experience, become afraid, and so the anxiety. I say it because indicas are used by people to control anxiety (and not to create it).

I dont know what exactly you expect from weed. If you could say your expectations, i would try point out the better type of weed (indica/sativa) for you try.
Anyway, keep trying. And, most important of all, let it go. Go wherever the "trip" take you. If you feel dizzy, enjoy the dizziness... If you feel confused, with the mind wandering aimlessly, enjoy it. Try enjoy the "trip", and im completly sure earlier or later youll be very well rewarded.

And as another people already posted, try doing some pleasurable things while high, like listening music, or eating chocolate (chocolate while stoned is the seventh heaven...), os just talking nonsense with a friend (stoned too, preferibly)... :stoned:
So, good luck, and keep posting!
