I took 3x 56mg tablets not prescribed thinking they were something else, I was very bad the next day with the side effect but have became a lot better I didn't sleep for a night and a day then got a full nights sleep. I still have a sore head and sometimes feel a bit sick but nothing major. I am just wondering if I could have effects for the rest of my life from this one time ? Should a go see a doctor even know I am better and it was 2 days ago ?
