dear Riss, this is always something that people are worried about, no different than to walk over a bed of hot coals, not that I have ever done that, but to start a new medication has to be decided by your doctor, and they do this because the old antidepressant (AD) has no more effect on you, and feel as though you are falling back into this horrible state, and certainly this isn't what they or you want.
They will start you off on a low dosage just to see what sort of side-effects may occur, but you have to remember that some of these will eventually settle down, however if they affect your sexual ability, then they should be changed.
Your doctor hit the right button last time with this AD so they will only try and help you as much as they can, even if it's a new doctor.
They will want to hear from you if this medication isn't working, but give it 4 or 5 weeks, whereas some people can get instant results, and how lucky they are, however there are times when people feel a sycophantic feeling at first that this new drug has instantly helped them, but after awhile this can wear off, so you should wait a few weeks to finally decide.
Good luck and please let us know. Geoff.
