Hi love im so glad you enjoyed your walk but not so glad that you are suffering.
I think you are on your 4th day and i was still suffering then...im on day 9 after my bypass and i started feeling a little better on day 6/7. Honestly lovey it will get easier and its terrible while its happening. Try leaving longer than the 30 mins between eating and drinking cos i wish i had, ive learned that im not suffering with any wind now as i leave a bout 45mins to 1 hour between eating and drinking....this helps me totally but we are all different.
Each day will get easier love really it does and when i felt like you i thought this was going to be with me forever, but it wont, trust me you will feel better again very soon.
Sending you a big hug as i can still remember how it feels, its shocking. Huggs. xxxxx
