I took 1 24 hour Allegra yesterday at 2:30 pm and i took 1 Benadryl this morning at 9:30 am, I’m terrified that I’m going to overdose. I was told by a pharmacist and everyone in my life that i will be fine but i do not believe  it, i still feel like I’m going to overdose. Im scared to sleep because i don’t think that i will wake up. For reference i am 18 y/o male and weight 240lbs. Anyone know how to make myself feel better?
