One year dieting and running became an obsession during a lengthy hypomanic episode and I was doing well enough when I crashed that I convinced myself to soldier on. I lost over 50# in a year and was running around 20 miles a week. My knees couldn't handle it and I ended up in surgery and they sent me home with some yummy pain pills and refilled them a few times during my slow recovery. That was a few years ago and I have recovered from the surgery and the drugs but didn't get back into a good routine and gained the weight back. Now I am bicycling and hope to get some off. The trazadone seems to be causing me to gain weight. I would really like to get off of it but it is hard to sleep without it.
