My doctor recommended I give Prozac a try for my OCD. I was on it for about 6 months, beginning with 20mg and gradually increasing to about 80mg (a high does of prozac is recommended for ocd). Well it did improve my ocd symptoms, but not enough to where I wanted to be on it long term. I began tapering off the prozac for a few weeks, then my doctor said that because prozac has a long half time life and I was only on it for 6 months I could completely stop. It has been about 5 weeks since I have been completely off prozac and I have noticed some changes and I am wondering if it is due to coming off Prozac. For example I am more irritable and moody. My OCD is also at an all time high, worse than before I ever began the medication. My main concern is I have noticed quite a bit of weight gain ever since I got off the medication. While on the prozac I gained a couple pounds (I wouldn't even blame the prozac) but after coming off nothing has changed yet the scale continues to rise and it feels impossible to lose. I was never depressed before, but this continuous weight gain has me discouraged, unmotivated and ultimately feeling depressed. Does coming off the prozac mess with your metabolism? And if it does will I ever go back to how I looked and felt before getting on prozac and if that is possible how long will that be??? Please help! I feel like even beginning the medication was one of the worst things I could have done!
