Hey everyone. a few nights ago i had quite a restless night of sleep, most likely due to the fact it was during exams week and i was pretty stressed. then my allergies began to kick in too. so overall i havent really slept very well in 3 nights now. im pretty tired, and my whole body just kinda feels weak during the day, especially today. i was taking tylenol to help with the allergies, and was wondering if that may be the reason i havent been able to sleep the past few nights. i have issues falling asleep, even though im tired, and once i do fall asleep it seems like i dont sleep well or wake up within a short period of time. i never had any sleep problems before the past couple days, and was just wondering if this is something i should be concerned about, or just something that will go away. i think my anxiety about the whole situation keeps me up a little bit too. any thoughts on what could be causing it, and if i should be concerned at all?
