Hi,
Thank you for posting your query.
I have noted your complaints. I would like to reassure you that there is no need to worry about your symptoms and you would get better soon.
For controlling your symptoms, you could take 
ibuprofen for relief of headache and 
betahistine for relieving your 
dizziness.
I would advise you to avoid 
smoking weed.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
