Ok, so I decided to make a Bluelight account just to ask this one question. So recently I acquired some 20mg adderall ir pills. I took 40mg for the first time last friday before school - yes I know a big first dose. I plugged 10mg (Questionable but it worked), I swallowed 10mg, and I snorted 20mg. I felt the effects pretty fast and it was great. It was one of the best highs i've ever experienced. I had a great day at school (One of the best ever), talking to everyone, being in a great mood, being productive, and just enjoying life. The come down happened around 5 hours later and it was pretty harsh but it was still worth it. I made sure I would only use adderall once in a while because I know it is very addicting. So a couple days ago I decided to stay home from school to catch up on my missing homework. I thought that I could achieve the same high with 50mgs. This time I think I snorted 10mgs and swallowed 40mgs. I started to work on my homework and didn't feel much at all. I was actually less productive then when i'm not on adderall. I didn't feel any high at all but I did feel a harsh comedown towards the end of the day. My eyes never dilated or any signs of adderall. When I went out to dinner that evening I felt sick. I had stomach cramps, nausea, diarrhea, and I felt disconnected and almost fainted a few times. My eyes were now dilated but no high ever happened. I was hydrated the whole time btw. I didn't sleep at all that night and stayed home the next day because of the stomach problems. My eyes were dilated and I showed side-effecs for the most part of 2 days. The harsh comedown also caused me to have some depression, and sad comedown-like problems for a bit. Did this happen because I didn't snort a lot this time? Or maybe I have a tolerance now? Please help because i'm very curious. Thanks.
