Was an amphetamine addict from the age of 14-28. I was self medicating and was a functioning addict, raising 4 kids. I remember feeling exhausted and weary and wondering how the hell I was gonna manage to get dressed without using first. I used to keep a bomb by the bed, then wake up at 6 take it then lie in bed waiting til it kicked in.
Then I would be up and dragging myself about gradually picking up throughout the day.

Anyway when I realised I had to stop, I made a massive effort with my diet and fluid intake since dehydration is a huge contributed to fatigue. Vit C helps you absorb other vitamins and minerals, water, and forcing yourself to go to bed at a reasonable time wether your tired or not. Also forcing yourself to eat, little and often. These were all things I did on the run up to giving up. The last bit is up to you also, cold turkey or reduction if your strong enough.

I managed to give up amphetamines. And havnt been back to them since. I won't make out I remained clean ever after because it would be untrue. However I now don't think I could stomach it now.

All the best for the future, take of yourself for your little.
