Side effects : Amitriptyline

I’ve started taking 25 mg and im not even sure why the doctor prescribed me this I guess for depression? anyways, after I started taking them I did research and it mentions a lot of severe side effects, keep in mind i’ve never taken any kind of antidepressants in my life so i’m new to this, but it got me thinking, do i have to take them everyday? and if let’s say I wanted to go on vacation and drink and party for a little and i missed a couple days of taking them then am i gonna start having suicidal thoughts and be even more depressed? it’s my 5th day taking them so i’m not sure weather i should stop or not, what are your guys thoughts about this medication and personal experience?
