My doctor put me on 75mg. of Effexor for depression. I have been on it for about 9 months. I mistakenly forgot to put it in my weekly pill container and did not take it for a week. During that time I was very hard to get along with, had nightmares, strange sounds in my ears and head, insomnia. I cried all the time, nothing I did was right. I just wanted to crawl in a hole. When I realized what had happened and started taking it again, the depression and side effects of withdrawal went away. It really scares me to think I may never be able to come off Effexor or will have to suffer the withdrawals. I think this is a very dangerous drug. I have been on anti-depressants before but nothing like this.
