taking a drug, to fix a symptom from a drug, to fix a symtom of a drug.. makes no sense to me
you get started on sleeping pills now, you will be on them for the rest of your life.
even non addictive herbs like N2sleep are not to be used for longer than a few weeks.. it even says that on the bottle.
there are many things you can do to avoid insomnia.
1. no caffeine or no caffeine past 1pm
2. reduce stress in your life
3. yoga, hot bath before bed.. relaxation
4. use your bedroom for sleep only, not to read/watch tv or anything else
5. get a decent bed and pillow, sheets, etc.. spend some money you spent most of your life there
6. don't eat too 2 hours before bed.
7. if tren still causes you problems then don't mess with it .. its that simple .. if you cannot sleep than you won't grow and its counter productive
