It took almost a year to forget I had had the op, mostly it was tiredness and fatigue, its major surgery and your body and mind has to recover, my advise is not to not rush things.
I remember in hospital I felt OK and on about the forth day I went for a walk as I was getting restless in the ward, I experienced an almighty hot flush all through my body almost icy hot, I never really had another one after that, I did have an increase in my sexual response in sleep!!! which was pleasant

and I thought I should have done this sooner, but it was short-lived and only lasted about a month. Many ladies report this.
While in hospital the ladies who had had an hysterectomy were given Voltorol suppositories because the cramping can be quite bad, I was given some to take home with me, the first night the cramping was very painful, I used a suppository which calmed it down and I never had it again after that..
Gas can be a problem too but the nurses will explain about this. You will be given instructions about wound care and a leaflet about any symptoms that would need you to get in touch with the hospital or GP.
Hope this helps.
