Started on 50mg of Sertraline. Awful side effects; dry mouth, felt sick, insomnia. Stuck with it. Went up to 100mg and had same side effects but only for 3 days and much milder. Now gone up to 150mg and feel so drowsy all the time. I take it in the evening as it spaces me out if I take it in the morning, but I find that by the time it's 7pm I can barely keep my eyes open. Has anyone else had this when going up to a higher dose of Sertraline? The plan is to go up to max dose so a bit nervous about that...
