Sertraline 100 mg side effects

I’ve recently gone up from 75mg to a 100mg and I’m not sure if I’m having a reaction to them. I’ve been really itchy at night like painfully so that I can’t sleep. Today I’m itchy constantly.

I’m trying to ride it out as it’s been less than a week, but I also have tinnitus and it’s making my tinnitus worse. I’m worried I’ll have side effects dropping back down as well. I’m going on holiday in just over a week and then when I’m back I start a new job. Not really the ideal time to be dealing with side effects.

Has anyone else experienced these? Should I ask to go back down or stick it out on the high dose. I really don’t want to be feeling horrendous on holiday.
