Southern bell-
Yes, my two pieces of advice-
1. GO TO THE BATHROOM BEFORE YOU START AND DONT DRINKA LOT OF WATER BEFORE

- its the worst having to go an hour in.
2. Dont stand up too soon...i thought I could get right up, fainted, and had a seizure my first time.
I have had it 60+ times, as I was using it therapeutically as you are doing now.
I used the veins in my arm EVERYTIME...and eventually they gave up and got sick of doing that...so if you do plan on doing this a long time, please try the cath as you veins may get sick of the treatment and prevent it from working.
please message me with any questions, but im sure your trying to get some sleep.
