My 70 yr. old mother started taking wellbutrin on March 26 2008. just to quit smoking. 150 mg. in the morning and 150mg. in the late afternoon. she did not quit smoking. I was noticing she was starting to kind of stagger when she walked almost as though she were drunk. and she would shuffle her feet and almost trip over them. keep in mind my mom is a very active, walks everyday very fast and looks 50! On April 17th she woke up in the morning and told me she felt very tired and just wanted to sleep. this worried me because this is not her norm. so I let her sleep. well she kept on sleeping. I went to work..came home and she was still sleeping!! I woke her up and she said she felt very panicky and was shaking very bad. I looked into her eyes and they looked jittery. She even said her left eye was very blurry. something was not right. I took her to the ER. They kept her for 3 days. did every test imaginable. every test came back perfect. no stroke,, NOTHING wrong!! she was sleeping the entire time in the hospital. They released her and said the only thing they could find was a slightly elevated thyroid. we have an appt. for that may 4th. so..as her heart is pounding and she is still very weak and can barely walk..they release her. she comes home and forces herself to walk to regain her strength. still on the wellbutrin. hospital still gave her it because we had no idea that wellbutrin was the problem. she had taken it many years ago and it was fine. she sometimes forgets to take it and she remembered yesterday that she had not taken her wellbutrin for a couple of days. so she took one. a couple of hours after that she began to shake again..her eyes looked weird again. she was very unsteady in her walking. very scared. well. today she is sleeping again. I am on here reading ALL THESE SIDE EFFECTS!!! I told my mom to gradually stop taking this pill!!! I really think this is what is causing all her problems. NO MORE WELLBUTRIN!! I will let you know how she is doing as she gets off this pill.
