I've been using for a long time but this situations is something new. a couple months ago I got a gram of 4-fa now I smoke weed almost daily but last week I consumed probably max 200 mg of 4-fa over the span of 24 hours kept me up almost 2 days straight. Probably started my use monday of last week in the morning and took my last dose 6 am tuesday morning. On wed night I went on a shroom trip with some friends. The next day I had this intense pressure in my head on the top and both temporal areas. This sensation is one I usually have after psychs but it never lasts more than three days. well its been about 5 days now and though the sensation is decreasing its still there. I've also went from dabbing and smoking weed everyday to smoking max of once per night and smoking wax only once a week (trying to get all of it slowly out of my system before a possible drug test later next semester) I suffer from some bad mental problems but ever since my massive weed intake reduction and last weeks use today I experienced what it must feel like to be psychotic. Just feelings of extreme anger depression and anxiety all which I've been using weed to suppress for 2 years. My biggest concern is the long lasting pressure sensation. also have been experiencing very weird and vivid dreams. Like I said I haven't completely stopped weed usage. also have been taking 5-htp religiously
