I've smoked weed before on late nights and woke up feeling like shit and a really bad headache but it was mid grade weed. When I smoke name brands I can smoke all day and everyday right when I wake up. you have to find the right weed if your nerves and stressed and get panic attacks I recommend using indica weed that wont raise your heart beat and it will calm you down. I smoke indica after 6pm and in the morning and noon I smoke sativa to keep me going.
