I Have BMS And I've Read Where Klonopin Is Effective

I have BMS and I've read where Klonopin is effective in treating this in some people. What dosage is prescribed for this? Is it a small dosage, so as to not cause side effects! I've read online there are several bad side effects & I don't want one problem to cause others by taking this if this is the case. I also take the maximum amount of Effexor, an anti-depressant & want to make sure there are no problems w/ taking both together. I also take Diazepam for anxiety & Nexium for digestive problems. I need HOPE for a treatment for BMS. It really is affecting the quality of my life! Is it okay to give Klonopin a try?
