I mainly increase the weight every workout, but I have reset the weight back a bit when I feel my form is deteriorating.
I dont think ill be able to increase the weight workout to workout for much longer, what ill probably try before going on the texas method, and you can try if increasing weight every workout is to much.

Workout 1
Squats 3x5
Bench 3x5
Deadlift 1x5

Workout 2
Squats 3x5 90% of previous workouts weight,(can go lower if required e,g 60%)
OHP 3x5
Row 3x5

OHP's and Rows are less taxing than Benchs, and DL's so using lighter squats as well will be a lighter, less taxing day than workout 1and should hopefully ensure a longer run of progress.
