Hello,Hopefully you respond soon,>I suffer from ADHD/severe Anxiety and panic attacks. My psychiatrist wants to use clonopin/xanax as a last resort. He had me on Prozac. It worked good except I constantly had diarreah every day. He switched me to Celexa. He warned me of the side effects and told me to contact him immediately if anything is wrong and he will try something else.He wants me to take 10mg at bed time for 4 days. If I can tolerate it up it to 20mg at night for 4 days. Then 30mg at night. Last night was my first pill. I only took 10mg before bed. I had trouble sleeping last night. I woke up in a complete fog and felt like I got hit my a truck. I took my prescribed 25mgXR this morning. It is not working like it is supposed to, I feel like the Celexa is overpowering. I'm extremely fatigued, can't stop yawning at the same time jittery, heart racing, chest tightening up, panic attacks, I am ice cold freezing. We have the heat on in my work. <>Am I over reacting? Is it just me going thinking to much with my anxiety? Is this normal? Is it just my body adjusting to it and will it subside? Do you recommend I call my Dr. Hopefully I will hear from you ASAP. Thanks. It's a shame because I just paid for the script last night. Waste of money seeing I don't think I am going to take it anymore.Is it possible for someone to have bad reactions to all SSRIs?
