Q. Does medication for ADHD cause restless legs, urge to sniff, and lick lips?

Hello doctor,

Last month, I had restless legs constantly even while resting, I feel the need to sniff all the time and lick my lips as I am getting accused of taking drugs, and it is embarrassing. I also feel a lump in my throat so keep trying to clear it, I do try not to do it when people are around but the urge drives me mad. I have had these symptoms for a few years but never as frequent as this, so I never thought it was anything that needed to be checked out but for over a month ago my legs were really bad at night and then got more frequent and now it is all the time, and my lips are really red, swollen may be sored from licking them. My legs go crazy even when I am in bed with my feet up and it causes sores. I did look up the symptoms and read that long-term use of Flupentixol can make symptoms worse. I had my dose of 12 mg daily for about two to three months, and I also have ADHD, psychosis, bipolar, borderline personality disorder, anxiety, and severe depression. The other medications I take are Procyclidine 10 mg daily, Venlafaxine MR 150 mg daily, Mirtazapine 45 mg daily, and Atomoxetine 60 mg daily. I am not able to sleep for days and the more tired I get the more of them and I do those things. I look like a mess and cannot face people and it is my family accusing me of taking drugs but I would not risk it with mental health disorders. What do you think it could be? Kindly help.
