Yup. Look, you need to do some research before you decide to take lots of over the counter drugs. There is a reason they are over the counter- taking enough for any kind of recreational use is usually a very bad idea. I'm not being a wuss, I've done it too...but you can cause liver/kidney damage and even failure (can't remember which or if it's both) if you take a lot of those. Stop letting your feenin' for a high get the best of you man, you're making bad decisions for no reason. Just chill til you find some bud or something else that isn't going to hurt you to get high.Kids today... you will sleep well and damage your liver and kidneys...
