I take 30mg Adderalls and after the 3rd or 4th day of taking them they seem to not work anymore but the most horrible thing after the 3rd or 4th day is that they cause severe nasal congestion, I am constantly clearing my throat or trying to get mucus up because it feels like there is tons of mucus stuck and feels like I am choking sometimes. I have tried Saline Spray, Sinus Buster etc... either they make it worse or they do not work at all. Does anyone else get this horrible effect from Adderall and any tips on how to stop it from happening at all or how to clear it up quickly? Thanks in advance.
