I'm 5'0 and 92 pounds. Last night I didn't sleep, so I took 1000mg of caffeine within a four hour period. I thought I was taking much less; I was very tired and read the bottle wrong. I've been dissociative all day. I'm not sure what to do. I went to school while extremely high and I had to hide it by making my heart slow down which actually made me feel like I was dying (which is why I'm glad I didn't have class second period). Will there be any major side effects from this?
