hello , i smoked bong on 6th May,2016 with some of my friends... it was my first time.. it was a terrible experience , i had a severe panic attack, but from the next morning i was feeling ok , i was ok till 20th may ,2016 ... on that day i took a nap on evening , but when i woke up i was feeling weird , since then its been almost 6 days , and i have been feeling cloudiness , like there is lack of light out there , i am having some balance problem a bit , and i had headache but its gone now but what is most annoying is that i am having some problem with my recent memory, like last night i visited my sisters house , and today i am feeling it long time ago , ,and there is feeling that i am not capturing my surrounding environment properly ,so now i am getting a bit worried , i mean quite a lot actually
1. is this normal for someone who has smoked only once in his lifetime?
2. how long this is gonna last ?
3. should i be concerned? see a doctor? my head feels quite heavy , and i m felling slow
4. i am sure its not in my head. and last night i thought i was improving ,and have a thought that after my sleep perhaps it will be ok , but today i am feeling almost same ... please help
