I have just taken first citalopram and an hour later started to feel like I was high and have user belly can't get off toilet is it normal
How long with high feeling last
Yeah the first time I went on Citalopram I felt like the ground was swallowing me up and I had a bit of a dodgy stomach. But after a few days it went away and I felt ok.
If it continues speak to your doctor, but it can take some time for your system to adjust. Also, just to warn you you can find yourself feeling worse (more depressed) before you feel better/ This is normal and just try to ride it out. (I'm only saying this so you don't panic if this does happen to you).
It can also take a few weeks to kick in (any anti-depressants, not just Citalopram), so don't panic if you don't feel any better within 1 week of taking them.
Remember that anti-depressants are trying to balance out the chemicals in your brain (at least this is what I was told). Hence why you can feel worse before feeling better. But it is worth sticking with it.
Your dr should also closely monitor you to make sure that they are working correctly and that you are taking the correct dose. Don't ever just increase your dose without speaking to your dr first.
Good luck! 
Thank you for your reply I appreciate your advice calmed down a bit it's starting to go away now don't feel in a trance anymore just gave me a scare
I'll bet it did! I wondered what on earth was happening to me when I experienced it.
Yeah it wasn't nice iv went round to my mums to stay the night (28 ur old man) lol
More than 1 in 100 people taking Citalopram Hydrobromide suffer with certain side effects including (but not least) diarrhoea and feeling dizzy.
It might be a good idea to report your problems back to your GP as soon as possible just incase they are considered unsuitable for you.
