Hi there. The trouble with all these drugs is that it does take the body some time to adjust to them and some do cause unpleasant side effects. There are lots of drugs that can help out there, and sometimes it takes a while for you to find the one that suits you. Its definately the right thing to go back to your gp and tell him how you're feeling, he needs to know anyway, and should be monitoring you anyway. It took me a while to find the right one for me, and now I take venlafaxine, but have tried citalopram in the past. What works for one tho' may not work for another !! Sp please have a chat to your gp, and maybe ask if he could assign you a cpn ( community pschiatric nurse ), they generally have a lot of experience if the various drugs used today, side effects and so on. If you have agood one they can be worth their weight in gold, and mine was definately a large part in my recovery. Hope this helps.
