I have recently started fluoxetine (about 6 weeks ago), I found the side effects absolutely dreadful.
I was nauseous, lightheaded, disorientated and exhausted, I felt like my head was going to fall off and all I wanted to do was lie down, I COULDN'T do anything else.
If I slept in the day I was wide awake at night so I started to take it at 8pm instead of in the morning so if it was going to make me feel wiped out at least it would be when I was sleeping. It does give me some freaky but realistic dreams though, the sort that you remember at lunch time and wonder if they are real or not. I had to ask my mum if a relative had really died because I really couldn't remember and I had dreamt hat he was still alive.
Totally fucked up my head it did.
Thankfully the side effects have now subsided, I can actually move now and have much more energy. I even managed to eat 3 meals yesterday for the first time in months. In the past 3 years my BMI has gone from 29 to 21 and not through dieting but from lack of appetite due to the depression. I can't actually remember the last time I enjoyed a meal.
I have been on the fluoxetine for 6 weeks now and I'm starting to see a glimpse of the person I used to be, I'm really looking forward to feeling better.
When I had been on meds for 2 weeks and went back to the gp because I felt so ill, I thought that it couldn't possibly be normal to feel this unwell. I was very tempted to change the medication but didn't want to go through it again acclimatising to new meds if there was a chance that I may feel better soon. I'm glad I persevered but it took quite a long time, feeling much better but not yet strong enough to get back to work. (there is no way I could have worked when I first started taking them, I felt so ill I thought I would crash the car).
I think I just need a couple more weeks and I will be ready to go back, just not right now.
Sorry for the very long post, I hope it helps and I really hope you feel better soon x
