I am a single mother of 2 children, I wanted to quit smoking so my doctor said to try Bupropion ER150MG for a 1 week and 3days The first week it was 1 pill a day then 2pills from there on out. The affects hit me the second day it has helped with cutting down on smoking and it makes them taste very plain and nasty. I have these systems/side affects already>feel slow, dry mouth, horrible taste in mouth, food and sodas taste nasty food has nasty taste as well and headaches first week. Very emotional ever since I started taking 2pills, just a thought and I would tear up. Like today this morning I was emotional and around 1o'clock I was Bitchy and irritable. I feel drudged honestly. Totally not me I only get emotional when on my period and Bitchy hardly ever! Sleep well lets say I wake up a couple times every night since I have been on it period. I am a deep sleepier too. I have no clue on what to do if I should give it more time or tell the doctor I'm done? I just want to quit smoking with something thats not going to affect me like this. I have no anger problems or anything like that just smoking. I am actually under weight for my age I don't know if thats why it has affected me so quickly 5'5 and weight 107-109 26yrs old I have not been eating as much as I usually do and have a high metabolism and I seem that I have gained a pd or 2. Don't understand I just think it's mess me all up. I waited an hr or two later to take my next pill tonight and I felt so good like myself, I will also say it seems to leave my system within 9 to 10 hrs it suppose to stay in your system for 12hrs but not me. If anyone can help me on advice feel free to email me please ******Thanks Mel
