Hi John and welcome. First off, I’ve added a trigger warning to your thread. It’s absolutely nothing to worry about, we just need to make sure that other members have the opportunity to avoid any threads that may be triggering for them

I am very concerned that your counsellor has given you a ‘diagnosis’ and ‘advised’ you wrt to medication. These are things ONLY a medically trained person ie a doctor should advise you of. This could amount to malpractice on behalf of your counsellor.

Yes, the mirtazapine will absolutely make you drowsy. It’s a side effect the majority of people will suffer from. However, the drowsiness should ease to a manageable level after a few weeks. If it doesn’t, definitely discuss it with your doctor.
