Withdrawal Symptoms After Miscommunication with Medication Refill

Due to a miscommunication, I've been off Guanfacine cold turkey for what will now be the third day and won't be able to get my refill until (hopefully) tomorrow. I was super ADHD yesterday (I'm not even actually on it for that...the thing it's supposed to treat didn't even seem to be affected) and somewhat today. But I've had horrible night sleeps for two night in a row because I couldn't get to sleep in the first place (New Years had no effect on this). I feel exhausted, and I tried to use my weight blanket but I haven't used it in a while so I woke up sore both days. I basically feel like I'm jetlagged. And some of this might be psychosomatic, or maybe I have a cold or something, but I just feel awful. I have my other medication and am taking it normally. And I did have a drink last night, which I know isn't a super great idea, but it was only one accross 2 hours and I felt like this yesterday before that anyway. Has anyone else had issues like this after having to hop off meds for a few days due to unforseen circumstances?
