For me the first thing I noticed was this chemical taste that stuck to the inside of my mouth for days. Can't get rid of it no matter how much I brush my teeth, use mouthwash, eat and drink etc. I never used it more than three days in a row but that was all it took to scramble my brain for about a week. Just constantly fatigued and unable to concentrate or think. Made work pretty much impossible.
I haven't but I'm open to giving it a go. I'll try anything at this point.
Thank you anon. I recommend it, easily the best monster movie I've ever seen.
