Hi all. Sorry I haven't been by in a while. I started taking Sertraline last September (25 mg for 7 days then up to 50 mg) and after some very, VERY brutal start-up effects, it finally started kicking in and I did pretty well from late November until this past week. I had some traveling to do for work and air travel is one of my biggest triggers and last Sunday I had an anxiety attack that kept me up all night. I made it through my travel week at work thanks to my Clonazepam (which I had weened off of in early December and only used sparingly when I knew I would get anxious), but I still feel like the anxiety is just under the surface and about to break through at any time. I had talked to my general practitioner when I started 50mg and told her that I suspected I may need to go up in dosage before too long, as I was on Effexor for several years in college and I had read that for people that start and stop SSRI's, it often takes higher dosages to reach the therapeutic effect. She said she was on board, but just to let her know when and if I decided to go up from 50mg. I think it may be that time. Does this seem appropriate to go from 50mg to either 75 or 100mg after only four months of usage? Should I start taking 75mg daily for a week then bump up to 100mg to make the transition a little smoother? I still have a couple refills on the Clonazepam, so I can utilize that to weather the storm of the transition, but I'd like to know if this is a good path forward. Thanks all.
