I would just take some smooth hits! don't try and rip them all the time! Also if you hold in your power hits too long, that could be a factor of how you feel also, because of the lack of oxygen going to your brain! If your symptoms continue i would call the doc to get some bloodwork done/ be evaluated my friend! You dont always have to be a power toker, it all works the same.....Keep me informed on your situation and take care buddy
